Posted sunday and the feedback was great. Original post about back fire and missing....now...stills starts ok, but dies out if I play with the choke I can keep it running...theres new gas and oil..cleaned carbs.. cleaned gas filter..BUT I noticed excess oil in prop and plugs fouled...Have oil injection...seems there is too much oil..when it runs smokes like hell, not normally like that. The oil bulb was loaded with oil...afraid to disconnect and run without oil to see if the oil injection system is bad (located under dash 3' from engine) oh yeah new plugs today and the same situation. I hope this is not a fatal problem...new fuel pump too last summer...thanks...FT NJ
