I have a 4 horse tecumseh motor on a tiller and i have took the cab apart cleaned ajusted everything by the book and still won't run without leaving the choke on all the time the motor runs fine while choked but that just not right to have to do that any help would be great thanks

 

Did you clean it in a bath type cleaner & let it soak for a while?? Still sounds like you have a blockage somewhere in the carb or the bowl screw. It should have (I think) 4 holes in it. The hardest to see is in the area between the threaded parts. Let us know some model numbers & I'm sure the pro's on here can help you!!
