I have a sno-tek 24, model # 920402. The RPM is throttling high and low. I purchased a carb kit and cleaned out the pins, but the problem is still there so I'm assuming the next step would be to replace the fuel lines. Does anyone know what size the fuel line is and a recommendation where to purchase? Thank you.

I'm trying to be more of a hands on guy rather than send it in for service. I've been bad in the past in that I didn't put stabilizer in during the summer and now I'm paying for it. I've learned my lesson, but on that note, it's forcing me to learn how to fix engines :)

:white^_^arial^_^0^_ I have a Sno Tek 724 but I don't have any problems w/it. You'll need an engine service manual probably, to get the fuel line size unless you contact Ariens. They can probably tell you.
Just a side note I don't think the fuel lines will help.

Yeah, I'll agree with Joe. Fuel lines are not likely to be causing the hunting problem. I think there are magical potions you can pour in the tank that may give some relief. I don't know what country you're writing from, Andrew, but the E10 gasoline found in the USA is not your friend in terms of long-term storage. Do you have access to ethanol-free gasoline?

I always use Seafoam and Startron. Others may disagree but I have never had any problems. I don't use StaBil.
Since my writing this several years ago the Liberty gas station near us begun sell Ethanol free 91 Octane. I have pretty much gotten away from using any additives since then. I still use 10% Ethanol 87 Octane when I'm running something constantly such as my push mower in the spring but if anything sits for a while it gets drained and run dry and get some of the E free gas put in the tank.

Weird, I didn't get any notifications for the replies. Thanks so much everyone, you saved me a lot of time. I'll try the Seafoam and see if I can get it to stop surging. If that doesn't work, I'll drop by for more advice.

I'm out in Canada by the way, Edmonton AB to be specific.

Mine was doing the same thing. I took the idle jet out and cleaned it up, that helped. These machines are jetted way lean so any amount of clogging will cause a hunting idle.

I have had stabil seperate then clod back together in the bottom of carbs..Years ago..I haven't used it since ..they may have changed the formula since then I don't know. I use seafoam now/ not that there is any scientific data to show it works...but by coincidence it seems to work for alot of people for off season storage.

I'd avoid the ethanol laced gasoline if at all possible. The stuff is **** on small engines, and not much better in large ones. I've used Stabil for years without any negative results. I use the new green formula in my boat motors as it is supposed to protect against ethanol. They seem to run just fine, so either it works or at the very least it isn't hurting them.

I’ve worked on many and I’m not sure the metric size but the stock low speed jet is .018 and I drill them out to .021 and all hunting goes away.
