thanks guys, very good tips , I tried the thumb over the muffler and soon began to see the fuel fill the carb. after that I cranked it a few times and got better results. but then the fuel ran back into the tank, so , Im going to remove the glow plug test it, seat it, prime it as mentioned above then if this doesnt work Ill just buy a new OS .40 to save time . thanks guys , I knew I could count on this site.
