The carburetor was rebuilt, all spec checked and double checked and operates great with no leaks. The gasoline in non-ethanol 87 octane a month old at 1/2 a tank. Stabil 360 was added to the fuel before adding to the tank. Tank is clean and new and all filters are clean. No residue. If it is rich, do I need to turn the mixture screw into say 3/4 turn from stop? Do I need a smaller main jet? Where to start?
