hi i have just bought a marine
hi i have just bought a mariner (japanese) 647s21730 it fires up easy but wont keep running until i restrict the air flow into the carby with my thumb. it looks as though it should have an air filter so i made one & now it will run but seems to choke down & splutter under revs does any one know if it should have an air filter or why it wont keep running without it any advise will be appreciated thanks
