Adapt a small carb (make a apapter) and use a small wallbro carb like on a G23 or a carb about the same size from a chainsaw. They hane a built in pump which can be run from crankcase pressure. May have to tap backplate. Will not need muffler pressure, or a cline pump. If anyone can add more that has seen this done, give us your results. Thanks Captijohn
