Put newly rebuilt model "B" on 54-3100. perfect. Runs but back fires. about 1/2 gallon of white gas on barn floor. Glass fuel bowl gasket bad. Would this cause the backfire? Hotrodlincoln, tc, Carbking etc. Doc. PS white gas does not grow on trees. Some of our WAWA and Shell stations are starting to sell. Our Stihl dealers here will not warranty any of their new products if gasoline with ethyl is used. About time.
