Small Engine Help

[karlvv30]

So I have a push mower that is 2 months old. I left some ethanol gas in there for a month and now it wont stay running. I know, I'm a dumbass. It will start just about every pull still. Is there any additives I can add to clean it out before I start running non ethanol gas? Thanks for the help.

I think I'll try some. Ill probably spray the **** out of the carb and air intake too.

Remove the engine and add a Honda one. Problem solved. lol

Seriously, try some Seafoam. If its only 2 months old, should do the trick. FWIW, i left regular gas in my honda engine mower for months a time and for years before I started taking care of it. Never missed a beat.

2 mo on ethanol shouldn't wreck the carb. Probably trash. Drain the carb bowl and see if that helps.

If it cranks, could be something as simple as gas tank vent not allowing fuel to flow. I have a 6 year old Honda that has only seen ethanol, and it cranks first pull even after sitting over winter, although I do add a stabilizer before putting it up. Fuel, air, spark... all you need and spark is proven by it cranking. Now focus on air and fuel.
