Easy Upgrades for your Stihl MS170

[Music] [Music] well hello again folks today I'm looking at the MS 170 you doing some upgrades see how these upgrades spec performance we're gonna be looking at change in the bar to a 12 inch bar and a new change adding a tunable carb doing a muffler mod bucking claw or whatever they're called on the side adding some timing to it another mod that is not performance but it's more of a usability mod is changing this from a front to a side chain tensioner all the parts will be in the bottom of these videos so let's get going so working on our bar upgrade the first thing you want to do is have a benchmark set so we can actually be cutting some cookies each time I do an upgrade and just to see if there's a real difference in performance so sharpen the chain all right [Music] [Music] [Music] [Music] [Music] so let's change up the bar this is a nice straightforward upgrade that anyone can do all right so here's the new bar it's a Holtz forma just a little 12 inch bar you can see difference between this one definitely is like a saw like four or five inches less to three inches four inches it's that's easy four five inches and the only other difference I can see these both have a riveted spinning nose piece this one has holes for greasing it other than that it looks to be pretty much the same see the Oilers line up nicely there's a new chain the only difference is it's a full chisel chain this was just a regular thing of peak routine this definitely is a more aggressive chain but it's a smaller bar so we'll see if that makes a difference and it is brand new so you know what this first comparison is in the complete apples-to-apples comparison but this will give me a good starting point for the rest of the upgrades the stock tightening screws right here watch the chain get tighter it's more of a pain to tighten then if we let the sighs OH still bury this so weirdly that's not better so whenever you tighten your bar always pull it up because you cut you're pressing down on it right pull it up take out any slack up that way the bar is as high as up as it can go Oh cut it [Music] [Music] [Music] [Applause] [Music] that's definitely a good improvement if you just need this for cutting small stuff this thing is already becoming a bit more of a mean little machine I'm looking forward to doing the other upgrades on it and see what really can we can really make this thing into so up next is the side adjuster the bucking spikes and giving this on a really good overall clean so I started installing the sided jester but everything is so dirty I kind of got sidetracked and then I started cleaning this area of the saw and then I got more side tracted and I started cleaning the whole saw so I'm just gonna speed it up a maybe a half a minute per minute of me cleaning the song and there's something satisfying about having a grimy dirty saw dusty saw look likes it clean and kind of do ish [Music] [Music] [Music] [Music] [Music] alright let's put on this bucking strip it looks like I ordered the wrong size stickers but I have some other screws here that should work and so we will go with them so now so back to the side adjuster you can see I took the original one out before I clean the saw it has its adjustment screw at the front of the saw which can be awkward to adjust here's the little part that changes it from a front screw which would have been right there to a side screw and you don't all you have to do is order this part you don't do anything else fits in there nicely because if you look at this boom it's right there you're done now it came with comes with this little plastic part here too which covers up the front for you it actually snaps in there nicely so after you put this in there's a little screw that's got to go in there [Music] [Music] now you got your nice little adjuster on the side alright today we are going to look at doing a muffler mod to this muffler or just replacing it with a free-flowing Loffler but first let's fire this thing up and see how loud it is [Music] alright this is just a 5/16 so taking off the muffler gives you a good chance to see the condition of the piston and see what score it or not and if that one is stuck a little you can see the piston in there so what you do is you just you pull it up and down and you can see the piston up going up and down and you'll also see if there's score marks on should just look nice and smooth here's the screen actually if you look at this one it looks slightly clogged so even just taking out the screen and cleaning it is a good good thing to do every once in a while looking at this muffler it's fairly free-flowing it goes straight through here over here we're gonna take this muffler apart and see if we can make it little for your flowing up alright so here's the muffler three parts but it forces the exhaust through there and then they can go up straight and out through the air but it also go down and around that way this is the biggest restriction maybe drill that out as well I don't think I'm gonna be doing anything to the inside I've seen other ones where they're all baffled but this looks fairly free-flowing so I think the PS holes here and open up these front baffles I'm gonna drill this out and then we will be opening these louvers a bit that's minimal that's a small hole for all the exhaust to come out of if I said this before but if you don't have a step get one of them there one of the handiest tools [Music] all right let's work on this I'm gonna first try just opening it up by prying it [Music] Oh like I'm bending this thing a little too much flatten that back [Music] see how this will fit on here now yeah I think it's gotta bend it a little straight again one of the best tools in your workshop is getting a good vise I just had to get this one because I had a cheaper one and it last me ten years and finally came apart and I wanted a new one and this this gave me the excuse to get a little better one wasn't that a crazy expensive ball put a link to it you can get a nice heritage vise like a snap-on at a yard sale or garage sale that's your best bet but they're they're hard to find that looks better [Music] let's start it up see if it's any louder [Music] you muffler mod let's see if that makes any difference [Music] [Music] [Music] [Music] [Applause] [Music] the next upgrade is going to be an adjustable carb this can be useful after making your muffler for your flowing and or changing the timing on your saw among other things so I've never really worked on this steel before so this is gonna be a little bit of a learning experience I haven't looked at any manuals but generally it should be pretty straightforward there we go let's get that out the way now this linkage pop it down alright so let's compare the old and the new it's still branded this is made in China h&L there's your low and high Jets and after you look at this carb they're right in the same location they're not really adjustable if I look in there I can't really see it too of that's gonna be able to adjust it so this is another opportunity to look at the condition of the piston except from the intake side oh nope you can see the Pistons going up and down when you can't see really any score marks I then realized with this aftermarket carburetor that the linkage could not be installed on the carburetor once the carburetor is mounted so you have to take the handle apart to get the linkage out put it on the carburetor slide the carburetor on and then put the handle back together all right but if you're working on these saws I went to get a good pair of cork screwdrivers I got these ends which are fine but you're always switching and I think if you just had a dedicated set of all the main t 20 25 and 30 you'd be pretty good or just get a full set I think actually this has to tuck underneath first so this meant that the carb had to come back off which meant linkage had to come back off and handle get the wire back under the curb then button it all back together so the next problem was with this linkage when I would hit the throttle I wouldn't get full throttle go 3/4 so I tried different things lengthening the rod but that just gave me more and more grief basically what would happen is the rod would hit the bottom choke bar that's going across the bottom another problem with bending it would just end up giving me about a quarter throttle to full throttle so basically it was somehow limited to about 3/4 of the throttle range so it could either go from a quarter to full throttle or kind of idle zero throttle to a three-quarter so I messed around with this for a while and then I came up with a different solution so here you can see the stock throttle linkage and you see right here it has slop so I took it out I had a small Robertson screw it was a little bit wider than what it was neatest so had drilled the plastic out just a little bit and then I screw this so now you can see with it in and you see there's there's basically no slop and now when I pull it it's right away full throttle and there's just a minimum there's a tiny bit but minimal that basically gave me the full throttle range from idle to full throttle and you know what if I'd done that straight from the start would have saved me probably a couple hours of monkeying with the throttle linkage of salford alright so you can see the fact she even comes with the adjustment holes in the airbox so let's drill some holes to it right here to get at the idle go right through this plastic I need a bigger there we go all right let's see if we can get it going I think we got gas I don't watch or whatever other teams up with you so we're trying to start and try to start I forgot to turn it on when I can get you sometimes today was a head of gas I've put it on the bench a little bit curved beam around fussing with the tuning screws and then I look like any gas that's all it is [Music] [Music] [Music] [Music] [Music] [Applause] [Music] okay now we're gonna do the cut with the new carburetor I don't think it's gonna make any difference but we're gonna give it a tribe's can you start it two hands oh oh let's try it I'll hold it better yeah put your foot there perfect [Music] [Applause] [Laughter] [Applause] [Music] [Laughter] [Applause] [Music] oh that's a good deal all right so now we're working on adjusting the timing this is an upgrade that is probably not for everyone it's probably relatively easy to wreck your sauce hopefully we don't do today [Music] see if we can get this out without locking up the cylinder a half inch so to take off the flywheel you first need to thread the nut back on put on a socket and extension so you want to lift up on the flywheel and then tap down on the socket so you have to give it a good sharp whack there's probably a lot more experts in me but the way the timing works is as this turns around was past the magnet which signals when to shoot the spark which is basically ideas when the piston is about top dead center and that's all set from the factory so by rotating the flywheel a few degrees counterclockwise the magnet on the flywheel passes the ignition coil sooner which in turn signals sparked a fire sooner effectively advancing the timing these saws ms1 70 have been told can use a little bit of a timing advance so the way to do that you can see you have your your key way right here you can look at the side as well you file down the leading edge so remember this turns this way the leading edge of that key way that way this can turn a little bit further that gives you a little bit of advance the research i've done people do between 1/3 and 1/6 of the width of this key way I'm just gonna start real small and then we'll go from there so of course I forgot to start recording just frustrating but all I did was take this file and file on the leading edge so let's put this back on this is stock this is advanced so you can see how much now you want to make sure that it's nice and smooth if it's grabbing you might have to do a little more cleaning up in there see how it slides back and forth nice and smooth and you know the seating surfaces fines so I put a rope inside the cylinder head with the piston bottom dead center just to hold the piston from moving up and down while I tightened the flywheel nut unto the crankshaft all right so now there we go now I'm going to tap this justice eat it and then going to keep pressure on it while I tap it and now we can put the nut on alright it's seated back down let's take it off look carefully we still have our timing advance so that worked so let's put this back together I don't know if you're allowed to take a chainsaw spark plug out with any other tool than this I don't know if you're allowed to there might be a law against it you don't think that's a law [Music] all right let's see if we need to do any tuning [Music] it sounds fine I'm just gonna leave it as is and do some cuts [Music] [Applause] [Music] [Applause] [Music] [Music] [Applause] all right folks that's the last upgrade up done I don't know my time on it I'll post the times and go from there so this is a nice little saw now put there with a little more power it seems like it's quicker if you own one of these saws and you just use it a couple times a year an easy upgrade would be the bar in a chain the other easy upgrade is a side tensioner and another easy upgrade is the front muffler if you do those three things you're gonna be happier with your saw if you're really into saws and modifications the carb upgrade well I'm not sure if it helped yet I gotta check those numbers but I think it did and then the timing now the timing is I'm putting a disclaimer here you know do it at your own risk you know if you do what I did and it blows up I'm not responsibility just a little sneak peek this is the other project that's happening I don't know if you've seen the other trailer video but I'm totally going over this trailer one last time it started with just some bearings and it turned into this so I imagine within a few weeks we'll have something on that well if you
