On your mods mentioned the pilot should be no larger then 138 and main maybe a 128 at most. Too rich mixture will eventually wash out your rings. Go online to pure-gas.org and look for stations in your area that have non ethanol fuel. The ethanol will kill a carb and engine. Stabilizers will not work with ethanol, don't care what they claim. Been there done that. The only fuel to use is non ethanol.
