I have a 50 that runs far better on premium non ethanol fuel. If I use the 87 octane, it runs like shite.

Try Sea Foam. People love that stuff.

Good luck.

got seafoam and will get ethanol free high octane fuel that may help because it does sound like detonation.

I am gonna service them too, but I think i may have figured it out the pilot air screws are broken off and can't be adjusted and the stop caps that keep them from vibrating loose are gone so they can't be correct, must have been the dumb arse that cleaned the carbs before
