Harley two stroke plug fouling
My harley 2 stroke has gradually started fouling plugs to a point i just a little use I have to change the plug. I would appreciate some trouble shooting techniques to determine the cause. Gas is mixed correctly. Thanks

What vehicle?
Could be a dirty air filter.
Could be the fuel or mixture.
Could be the oil you are using.
Could just be a old plug that needs replacing.
Could be running too rich.
Could be not enough compression.
Could be a blown head gasket.
Could be the choke is still closed or partially closed.

I just went thru a similar headache with my old Cushman engine recently.. Fouling plugs in a day or two. turned out to be dirty fuel. Had to clean plugs, carburetor, fuel pump, line filter tank filter, and the fuel tank. I now filter the fuel AS I fill the tank from my fuel supply cans.
