Good vid. In the future, I would recommend treating your fuel before you even pour it in the tank. Where I live in New York, non-ethanol fuel is unavailable. So I will add 1/2 ounce of SeaFoam motor treatment, and 1/2 ounce of Sta-Bil 360 per every gallon of gas I use.
Thank you. I just picked up a really nice 5 year old 2620 for $450. It runs great, but it does have a bit of surging. I will definitely be cleaning out low idle jet.
It is the ethanol blended fuel that causes carburetor problems during storage. Ethanol absorbs water and causes corrosion and gunk to build up in the jets, emulsion tube and float bowl. Sense I started using non ethanol fuel along with Sea Foam in all my outdoor power equipment, my carburetor issues during storage are no more. If non ethanol fuel is not available in your area, it would be a good idea to use some engineered small engine fuel to run through the fuel system before storage. Some say use 91 octane in all outdoor power equipment to alleviate carburetor issues. Small 4 cycle engines are relatively low compression and don't need slower burning high octane fuel. It is the extra detergents in the higher octane E10 fuel that makes the carburetors stay cleaner. Premium fuel still has at least 10% ethanol. Where I live in southeastern MI, 89 octane non ethanol fuel is about the same price as 91 E10 fuel. Nothing worse than the snow blower not starting because of a clogged-up carburetor and a snowstorm is on the way. Sea Foam is a great product to help dissolve varnish and allow it to pass through the jets. That is why it is recommended to be used on a regular basis, one ounce Sea Foam per one gallon of fresh fuel in small engine 2 and 4 cycle engines. If your carb is surging or only runs on half or full choke, Sea Foam recommends a dose of 3 to 1 mixture and turn the engine over to pull the concentrated mixture into the carb and let sit for a day or two to allow the Sea Foam to dissolve the crud. Then, if the engine will start and stay running, run the concentrated mixture out before adding fresh fuel with the regular one ounce of Sea Foam per gallon of fuel.
Thanks a bunch for sharing that video! I actually live in Michigan too, in Rochester Hills. I ran into the exact same issue with my used blower. It's been around for about 3 years, and just yesterday, I noticed this rough idle sound. I tried taking apart the carburetor jet, but no luck. Then, I stumbled upon your video and followed your tips. It worked like a charm! The issue is completely gone now, and I'm so happy I found your advice
Thanks fot the video. Mine wouldn't start this year so i dropped the bowl and pulled the jet up in and got it all back together and it fired right up. I was excited till i realized it only ran with the choke half on haha
My model is a "yardworks" but the engine looks the same. I was told it's basically a MTD . Will try this on a warm day. It surges on full speed and wants to stall-out when I slow the throttle down below about half way. Sure hope this works. Clay Oh I already took the bowl off the bottom and cleaned that.
Isn't the idle screw just a stop for the throttle mechanism rather than an adjustment for the jet that it holds in? Also, I don't think the presence of the idle jet has anything to do with EPA regs.
