HOW TO ADJUST SNOWBLOWER CARBURETOR

hi today I'm going to show you how to adjust the carburetor on your snowblower before we get started I want to show you two types of carburetors that you may find on your snowblower with the tum engine on some of the old snow blowers which would probably date back to prior to 2002 you will more than likely find an adjusting screw at the bottom of the Bowl here this is the fuel mixture screw right here you'll also find another screw here here on the side of the carburetor this screw here which is a slotted screw is called the idle mixture screw and this screw here is to adjust the speed that you want your engine to idle at when it's throttled down on some of the more recent snow blowers with the come engines you'll find a carburetor that has no adjusting screw at the bottom it's actually a fixed jet this bolt here is actually the the fuel jet for this carburetor and you'll notice that there's no screw here where the idle mixture screw is on the previous carburetors there is however the screw here which is a Torx number 10 to set the idle of your engine this little valve here is a dump valve from when you store your carburetor you turn your fuel valve off on your gas tank push on this it will drain the carburetor of the gas so that it doesn't stagnate in there and cre problems for the following year now this snow blower here has the older type carburetor with the screw at the bottom as you can see under there now it's not necessary to remove this cover here that covers the carburetor the reason for that is that there's two holes here there's a hole here to set the idle speed on your engine and there's another hole here to reach the idol ID mixture screw if you look in there you can see my Torx wrench is where the idle setting for the engine is you can reach that from the upper hole and you can see my screwdriver here which is moving on the idle mixture screw which I inserted through the lower hole of the casing covering the carburetor so just to show you here you can see the screw through the hole I've got the idle mixture screw here set at one turn and a quarter it's usually good there you can leave it there and then simply adjust the main fuel adjusting screw at the bottom so to do this I'm going to start the blower I'm going to rev it at full speed and I'm going to turn up or down the fuel mixture screw until it runs rough either way so until it runs rough when it's screwed in too much or screwed out too much and then I'm just just going to reos it in between those two spots now I've got this screw here set at a turn and a half out the way you do this is by screwing it in all the way up and then counting your turns out so one2 one turn and one and a half and now I'm going to play with with my finger you don't need a screwdriver cuz it's fairly easy to turn by hand and I'm going to set it to the position that it runs the best with the engine at before setting your carburetor make sure that the engine is [Applause] warm [Music] if you tighten up the screw too much like I just did and it stalls like that just unscrew the screw a bit star her backup so now I'm going to show you how to adjust the idle speed by inserting your Torx screwdriver in the upper hole on the cover so I'm going to start the blower again let it idle and insert my torqus in there reach the screw in there if you turn the screw in the engine will idle faster if you unscrew it the engine will idle slower so I'll just do a quick demonstration of that when you adjust the idle on on your engine make sure that the sleever is in the notch here not all the way down but when you're running it just lock it in that Notch that's the proper idle position and then adjust the screw for the idle setting now after you've done all this if you still have a problem to get it to idle properly you'll need to adjust the idle mixture screw which you can reach it with the flat screwdriver as mentioned previously by inserting it into this hole at the bottom here and either turn the screw in or out until the engine idles properly without too much hesitation but I've set it at a turn and a quar you may be able cat one turn out as well but it runs good for me at a turn and a quarter and I've got the adjustment at the bottom made so I'm going to leave it the way it is like that at high speed and it idle good when you've got the throttle down she's good to go if you find that your engine doesn't rev high enough at high speed there's a little screw near the lever here that little screw that you see right there which is attached to the lever it's usually a torque screw screw or slotted screw if you turn that screw in the engine's going to rev at higher RPMs when this sleever is all the way up if you loosen it it's going to turn slower when the sleever is all the way up I've got another video entitled how to adjust the engine speed governor on your snowblower please go watch that video if you need to make adjustments to your Governor uh that video describes it in more details and for today you should be able to adjust your carburetor by watching this video I've tried to make it as simple as I could so that anybody
