I have a Craftsman walk behind with a 5.0 hp Tecumseh engine. It runs, but horribly. Spits gas out air intake. I have had the carb off, soaked in cleaner & rebuilt. The carb has been off & on at least 5 times. I don't think the carb could get any cleaner. Engine model # 143.975012

[FONT=Times New Roman][SIZE=3][COLOR=#000000]Hello, I have a Murray model # 20213B with the Tecumseh engine. I have a starting problem, it would take 50-75 pulls before it would attempt to kick. I just rebuilt the carb and this thing still will not start cold. I will pull it for 50-75 times, it won't even kick. Pulling the cord for 50-75 pulls will not flood it, though, and it will eventually start. I think the primer is working, without the air box on, when I push the primer, I see some fuel come up out of the tube in the throttle body assembly. Spraying some carb cleaner directly in the throttle area wouldn't make it kick, either. There is spark, because once it starts, it will run all day. Also, once it has run, it will restart with 1 pull every time. Once it cools off, it will not start. Thanks for any advice[/COLOR][/SIZE][/FONT]
