Ok then with only a gallon of fuel thru it, the engine should still be in good shape.. well I would have to say do the OFNA Checkvalve mod first then retune(lean both high and low speed needles) and be sure you are running the OS #8 plug or equivelent. This should help tremedously!!

Let us know how it works outs or feel free to ask ANY questions you need to, to get her running well..
