Insane Carburetor Project!!

just for the heck of it I'm gonna polish this carburetor to a mirror shine now I'm not usually a fan of polished aluminum but I think it would look cool on this carburetor now it's been about 10 or so years since I've brought aluminum to a chrome-like finish so bear with me as I knock off the rust so there's a few things I want to pull off just to make the polishing process a little bit easier mainly the choke a few of these screws and the cable guide up on top this is what I'll be using to knock out the polishing it's got a little electric dremel tool along with the accessories that came with and then a crap ton of other polish and supplies I've had around the shop alright roll up your sleeves boys it's about to get dirty the first attachment I'll be trying out is this little cloth wheel and also supplied in the kit was the stick of polishing compound and with any grinding or polishing project you gotta wear a respirator I'm starting to realize this is gonna be a ton of work a lot more than I was hoping for it wouldn't be bad just polishing out the football but the carburetor body itself would need to be sanded down because it's got this casting texture on it and all that would need to be knocked down in order to polish it out to a mirror shine so what I'm gonna do instead is pull the carburetor completely apart polish the football and the throttle cap and then seracote the carburetor body this should look pretty cool now I've got the carburetor completely apart it is gonna be so much easier polishing out the football and throttle cap over on the buffing machine first off I'm gonna clean up these two pieces with a scotch brite wheel and what this is gonna do is remove some of the scratches smooth out the finish and get it ready for the first stage of buffing I've got some ridges here on the edge of the football and some deeper scratches that I'm gonna take care of with the sanding drum the first stage of buffing will be with what they call a sown wheel and a triply compound so the wheel I was using earlier this one right here actually is not a stone wheel this one on the buffer is indeed I came across it in the cabinet and it seems to work a lot better a little more aggressive after the first stage this stuff is starting to take shape but you just wait until the final stage is done and that will involve using a loose style wheel along with a white Rouge not bad at all it's gonna clean up some of this buffing compound may be touched up a little bit and then call again well guys I am gonna have to call that done polishing definitely is not my strong point these things did not turn out quite perfect but you know what it was a fun little challenge and I think it'll still look pretty cool all put together next on the list is prepping the carburetor body for sarah coding if you guys want to see the entire sarah coding process explained in a video just click the circle right up here in the corner so basically the sarah coding process is first starting out by soaking it in acetone for 30 minutes then Sam bossing it followed up with a preheat at 300 degrees for a full hour then spring up the seracote and then curing the seracote back in the oven for another hour since there's a few areas that do not want a sand blast or seracote I'm gonna have to do some masking here that was actually a whole lot of masking I don't know why I've always enjoyed masking though next up is Sam blasting I went ahead and touched up some of the masking since parts of it were peeling up from the sandblasting and I wanted to get all the sand out of the inside of the carburetor one thing I need to do before I run this part through the oven is cut some slits here in the masking tape that way doesn't shrivel up in the oven all right I've got the carburetor hanging and it's ready to go into the oven for the preheat process which will burn off any remaining oil and residue this is what it looks like when you don't cut enough of a relief into the masking tape it'll shrivel up in the oven once I fix this it'll be ready to spray uh-oh as I was masking I noticed there's some oil or some sort of residue coming out around these screws so that's an indicator there's still some oil or something left in the material and that'll have to be removed before I spray so I'm gonna wipe it down with acetone once again and then bake it in the oven for another hour now I've got a lot of oil coming out of these screws so I'm just gonna pull them out and wreak lean the whole carburetor completely frustrating I'm actually glad I went through and pulled this thing apart a little further now I know 100% is not gonna be anything leaking out and ruining that sarah coding so now we just need to soak it in acetone mask it off again and then preheat it in the oven and it should be all ready to spray after that finally the carburetor gassed out fine and there are no signs of any oil residue time to mix up some seracote and spray out the carburetor so I've got two seracote colors here a burnt bronze and a tungsten and I'm having a tough time deciding between the two I know I can't go wrong either way but just hard to know without having an actual part spray it out with either color in front of me hmm I'm thinking for this carburetor a bronze is gonna stand out more the tungsten is kind of like a charcoal color so it's not gonna be like that far off of what color it is already so I'm just gonna go with the bronze all right I've had the carburetor in the oven for an hour now and it should be all cured and good to go check that thing out for you guys I love the look of seracote and want some work done make sure you get a hold of Clayton over at trick engineering super good guy he'll set you up with some really good pricing and work I'll put his info down below all right I've got the carburetor in a million pieces and it is now ready to go back together thankfully All Balls Racing sent over a carburetor rebuild kit and it looks like it's got everything I need to completely overhaul the carburetor all right let's get this thing back together a lot of times my projects don't really go to plan throughout videos things will come up I'll have to shift things around but there's always a workaround I just hate given up on a plan or a project but with this carburetor I think it would look pretty cool I'll polish it out but it should look even better with the sarahx coated body and polish flow bolt and cap we'll see how it turns out so it should be pretty straightforward bolting this carburetor back together the only thing I'm gonna walk you through is setting the float height so how I'm gonna check the float height on this carburetor is by setting it level and letting the floats extend to their full length so they're the art extend it all the way out and then I'm gonna let the floats return to the resting position so right there so it's not pushing in the needle or the valve just resting right up on top of that plunger so when I push the floats down that is compressing the plunger on the needle valve there so we want it resting right up on top so I'll do that once again so right there it's at its resting position and if you can see there's a line on the floats here that should be parallel with the football line right here on the carburetor so when the floats are in the resting position right there we need those two lines parallel so this one is just slightly off and to adjust that I'm gonna bend the tab on the float just a little bit so in order to get the floats level with the football surface I'm gonna have to bend this tab right here the tab up the needle valve is hanging from I'm gonna Bend that up just a smidge it really doesn't take much to make an adjustment here all right now let's check it again so that is looking pretty parallel right there I'm gonna call that good so if your float level is too high meaning it's right about there you'll need to bend that tab down instead of bending it up setting your float height is something you definitely should not skip if your float height is off it'll pretty much nullify any jetting changes and it'll really affect the way the bike runs so get it right the first time you if you guys would like to support what I'm doing with this channel I actually just got some more stickers in stock head over to prime Memex comm and grab your stickers so all balls provided a new needle with this kit and I'm gonna go ahead and set the clip position in the same spot as the original one so this one is one down from the top and how this works is if the clip is farther down that'll richen it up and farther up will lean out the bike a lot of times new o-rings don't really want to stay in a place so applying a little bit of grease will help that out and this is where the mini grease gun really comes in handy I can put the grease exactly where I need it and I put a couple dabs on this cover here of course I'm gonna have to pop the cap off to get the thrall cable on but I figured in the meantime might as well see how it looks and steal the carburetor up a little bit I also got a new air screw as well I'm gonna go ahead and install that now so the factory setting for the air screw is one and a half turns out from lightly seated I'm gonna turn this thing all the way in until it seats and then go one in half turns out alright right there is seated all the way you go half one and one and a half and so what the air screw does is it controls the mixture from closed to about eight turn to the throttle ideally with this two-stroke carburetor you want to be between one and three turns out if you're below one turnout you need to go larger yep larger on the pilot jet and then more than three turns out you want to go smaller on the pilot jet and that last of all we have the throttle stop screw this is what controls the idle and this screw needs to be set with the engine running so I'm just gonna set it about where it was when I pulled it apart and that should be I want to say like two or three turns out alrighty guys that is gonna be it for the carburetor assembly turned out absolutely wicked definitely happy with it real quick just gonna pick the winner of the giveaway from that last video go ahead and tally up the comments here looks like we've got 373 when I hit start it's gonna pick a random comment from that video all right Tyler Reece says Honda right on man all right Tyler message me with your shipping address here on YouTube and I will get this master cylinder kit over to you hopefully you can use it if you guys enjoyed watching this carburetor get all decked out make sure you smash that like button all right thank you so much for watching everyone you
