Very COMMON problem TORO LAWNMOWER needs work! WATCH a complete CARBURETOR Rebuild TECUMSEH Engine

[Music] yeah it's been a while since I've battled chickens while I was fixing mowers but we're gonna do that today give you guys some entertainment today we have a Toro lawnmower it's a 6.5 horsepower to come some engine very common to come say engine design Toro made a million of these and you may have won so I'm doing a tune-up on this and one of my steps to doing a tune-up is to clean out the fuel system in the carburetor I've already removed the float Bowl on the carburetor and drained the gas tank and I'll show you what I found so it's just a half-inch socket to take off the float Bowl and then you have this little brass component here which is your main jet and then you have your float bowl you can see the float Bowl is fairly clean this lawnmower actually ran pretty good but when I took the float Bowl off there was some stuff in there so I'm going to clean that out but more importantly what I noticed was that on the main jet here I don't know if you can see that but inside that's part of a ring that must be damaged up to up inside the carburetor because it's starting to deteriorate as you can see so what I'm going to do is show you how to rebuild this carburetor luckily we don't have to do too much cleaning on it but we will replace all the rubber components and o-rings and the float valve and that sort of thing so get prepared and so once again the fuel system is clean that's a very important step whenever you're rebuilding a carburetor is to make sure you have a clean gas tank so to remove the air filter it just twists and pulls off and we'll be replacing this air filter also as you can see it's in pretty rough shape I'm going to take this engine cover off just so I can get a better look at things it's a quart four quarter inch bolts you also have to remove the oil dipstick to get this red cover off and then this gas tank at this point you just rock it back and it slides out of place there and now we're going to remove the muffler those are 7/16 inch bolts okay now we can get to the bolts to take off the carburetor so what I usually use to remove this is a 3/8 socket with an extension and a 7/16 inch wrench wrench goes there easy enough a this back bolt can be kind of difficult to get to sometimes I've had to dent this cover in before push it in a bit just so I can get back to it let's see if I can reach it here I'm just gonna slide this gonna move this out of the way and try and get my wrench down onto that nut yep I got it and you can reach there two bolts and this carburetor is off of there to get it off this linkage you have to rotate the carburetor sometimes it can be difficult to rotate the carburetor if you still have the fuel line attached so I'm going to take that fuel line off of there this is just a breather hose so you can just pull that off of there ooh I almost damaged that gasket be careful not to damage that gasket all right so I have to clamp off and wiggle the fuel line pull it off now I can rotate the carburetor like this comes right off and I always mark on here which hole it came out of you see back here you have a little bracket and spring mechanism make sure you don't displace that that is how we'll adjust our final rpm well you can see I dropped the carburetor in the dirt so it's a little dirty now but overall I don't see any rust in there it looks like this oh ring will need to be replaced I might be able to clean that off and reuse it if it's in good shape but up in there is where that deteriorating oh ring is and there's actually two o-rings up then up in there that you need to replace we will want to clean up all this crusty stuff around the edge and the rest of the carburetor for that matter just to make sure things are clean before we go back together I think that uh that gasket is still good I just need to be careful with it it's not broken so we can reuse that I'm going to reuse this one but if you want to replace yours go ahead dad I see you sneaking up on me well folks I got to go get some parts I won't be long all right we're gonna move things from there to here and I'll show you how to do this and this is the carburetor kit I could see it comes with the new needle float bull gasket and a seat and gasket for the main jet and the part number from Tacoma is 6 3 102 1b and this is also a special tool you can get from to come so you don't need to use this to take out the the seat but it sure comes in handy hopefully you can see on this end there's a little hook and on this end is where you put the seat for installation and you press it into place one of the first things we need to do is take out the nozzle the red plastic piece in there which has the o-rings on it and to do that mmm I just go in open that throttle plate go into the carburetor the long screwdriver and push down on it hopefully you can see it in there see the red piece that's what you want to push down on and it comes out through there that's starting to come out and if you have a pic or something you can get down in there and pull it out mmm sometimes it can be a real bugger to get out of there I can usually get it out with one of these doodads one way or another oh there it is so this is how it usually happens you see that's the o-ring that was falling apart that the main jet showed but you also have an o-ring that goes up on here and it usually gets stuck and it did this time you can't really see it but it's stuck way up in there so I use my pick to get in there and you don't want to scratch things up too bad sometimes they can really be deteriorated up in there I think I see it coming out yeah okay see that oops so there's the other row ring hmm they're both the same size the part number for the smaller rings is 6 3 2 5 4 7 there are holes in this little nozzle you want to make sure it's not plugged up and the new o-rings go in place just like that and like that all right it'll take the float off you just pull out the pin and float comes right out of course I want to make sure to clean all that dirt off that I got on there and the float and the float needle just slips right off so I'm looking at this carburetor and it's actually in pretty good shape you want to make sure that you clean things out very well on this carburetor I got some dirt on it but I'll clean all that up luckily we don't have any rust in here you can see the primer bulb is still in good shape it's still soft and squishy we do have a component down in that dirt we need to get to on most of these carburetors that's where your your SLO jet is so you got to clear that dirt away and you have a little black cap plastic cap see that and I usually just poke a hole in it like so with a pick and pull that off and now you can see you can remove the SLO jet with a flat head screwdriver be careful not to get any of that dirt down in that hole it's probably a good idea to clean that dirt off first okay so here we are here so here we are here's your slow jet as you can see you have holes that go through it there and you also have a very very very tiny hole through there so you need to make sure that you poke something down in there I usually use piece of wire to clear that hole out and these side holes to make sure that this jet is not plugged up very important and I can see it going through there and I want to clear out this hole as well okay nice and clean we're ready to go back in but we also want to make sure that our hole there is not dirty and if you look down inside that I don't know if you can see it there's also a tiny hole that you need to make sure is clear and you can use carburetor cleaner or air down in there to clear out those passageways that helps and with this screwdriver I can scrape off a lot of this crud that's on here a lot of times you have remnants of the o-ring down in down in there and you need to use a q-tip to clean it out but I can tell it's it's clean down in there so a little bit of carburetor cleaner is probably all I need now here's where we use this tool we we go down in here and we just poke see the little hole a little white rubber seat down in there we poke this tool down in and we hook that seat and we pull it out and we clean out that area as well make sure that's good and clean with a q-tip there's also a hole down in there that would be a good idea to clean out as well with some carburetor cleaner things are starting to look really clean and ready to go back together mmm carefully put this piece in and make sure not to knock any dirt back in the hole and you don't want to over-tighten this but you want to make it snug these jets do break easily so give them snug put the little cap back on okay now to put the nozzle down in place I like to spray a little bit of wd-40 here down in the hole and it goes in this way just push it down into place be careful sometimes that o-ring can pop off of there when you're pushing it down into place there you go we're all good now we need to clean out this jet oh yeah I see that that came under there that was a piece of that o-ring so you want to make sure that that hole down in there is clear as well as these two holes on the side one on each side I'll also spray a little bit of wd-40 down in where the seat goes I don't know if you can see but on one side of the seat there's grooves and on the other side it's flat so you want to make sure to put it groove side towards the metal so this is how we'll install it okay see that groove side towards the metal so we basically just stick it in place and press it in we don't have to go real hard but we want to make sure it's good and seated there we go okay and we'll put the gasket back on now that I've cleaned off the carburetor okay now when you put the float on you have to adjust it so you have to put the clip on your new float valve or float needle and I've cleaned off my float and I don't think it really matters which way you put the clip as long as it's stays on there the way it's supposed to be on there which is like this if you could see and you simply got a hair on there and gotta get out okay then you put it in place oops sometimes it can be takes a couple a couple times do it put your PIN in alright now you double check to make sure that the float is are the you want to double check to make sure the needle valve is still in place the way it's supposed to be and this one is now you can see this float needs an adjustment what you want to do is hold your carburetor upside down like this and you can see how it's a different gap on that side versus that side you need to bend the little tab on the bottom of the float over here we want that gap to be even so see the gap over here it's less than it is over here we want that gap to be even so we get a long screwdriver stick it in here bend that tab down a little bit now the float it's adjusted perfectly because we have an even gap on each side I want to make sure the clip is still in place which it is and that's how you adjust the float just like that the float Bowl goes on a certain way see that line in the flat spot that goes even with the hinge pin so you want to install it right about like that you see what I mean that flat spot needs to be where the hinge pin is just like that our main jet is good and clean I've got an gaskets on there still good so we're going to use that okay you want it you don't want to over-tighten it but you do you want to make it good and snug so all the gasket surfaces seal right about like that this carburetor is ready to go back on the lawnmower oh right so hopefully you remember it which pull you took the linkage out of I did because I marked it turn the carburetor like this put it in place don't forget the gasket so a lot of times what I'll do is I'll just get this I'm not started first have the carburetor carburetor tilted that way cause it's easier to get to so get that nut started first make sure the gas gets in place put the breather tube back on careful not to knock any dirt into the carburetor Inlet I'm gonna tighten these down good and tight and I mentioned this little bracket and spring right here you want to make sure when you tighten things back up that it's it's pointing straight up like that okay and we could put this muffler back on you want to be really careful when you tighten these up because it's really easy to break off this little tip so you don't want to over tighten the muffler bolts and I just kind of wiggle it around while I'm tightening them up to make sure it's good and centered remember not too tight you break these off you're gonna be hating life ah there you go good and tight but not broken okay so now the gas tank goes back on I replaced the fuel line because the old one was cracked alright let me just slide it back into place and we're good new air filter part number three six nine oh five goes in like goes in this way slides on and rotates into place not too tight and break the plastic okay hopefully she holds gas and doesn't leak out the carburetor okay we're gonna fire this thing up and adjust that carburetor like I was saying prime it a few times you have to give the gas a little bit of time to get into the carburetor so it runs pretty good but I want to wrap it up more so I'm going to show you all how to do that okay so by bending that bracket there that way it actually tightens that spring and causes the engine to rev up more if the engines revving up too much you'll Bend that bracket back the other way I'm just going to and nudge it to tighten that spring alright you can see I bent that tab now now let's fire this thing up and see [Music] I think that's a success thanks for watching folks
