Agree with the above. Non-stabilized fuel craps out a carb around here in a matter of months. I *always* stabilize the fuel with Marine Sta-Bil.. Not saying that PRI-G isn't better.

I will seek out non-Ethanol fuel where available and I'm willing to pay more for it. I stabilize on top of that.

Pilots seek the fuel you're looking for as "MoGas" - there are a few maps on the internet of where to find it (non-ethanol unleaded).

In a pinch and for some motors, I run 100LL (Aviation fuel) which is designed to set for much longer periods of time. It'll produce slightly less power and some motors like it more than others. It's also more expensive, but I've never had a carb gum up with it.

Seafoam, in my experience, will not do much for a carb that's crapped up. Your existing crapped up carbs can be rebuilt by someone that knows what they are doing - usually starting with replacing the idle and main jets....
