Im at a lost, My 16 hp tecumseh OHV surburban will run at high idel when choked, but When I push the choke in it wants to die. It also seems to die when Im runing the mower, twice Iv done two passes in my hard and it just die. Thinking I need a carb kit, I just put a new fuel pump on it. Maybe theres some muck in the carb. Iv cleaned it three times but maybe I need to let it soak a couple days in somthing. Any Ideas???
