    I have a Craftsman 917377651 self propelled mower with a Tecumseh carb. The mower starts fine but won't stay running more than a few seconds. If I press wth primer button and keep it pressed in it will keep running. I have tried cleaning the carb. Have taken it apart and sprayed gunk removal on all parts. I took of the brass screw, cleaned out with a wire all the small holes but nothing with get it running properly. My guess is the brass trottle plate on the top of carb that is held by the wire rod that goes to the connector (not sure what it is called) is causing the problem. It seems to float in and out while running. Could the spring be damaged causing that part to not work properly? I have tried buying a new Tecumseh carb on Ebay, which seems to be the most reasonalby prices, but they don't sell the two connecting rods with the carb and I am concerned that I may have bent them taking the carb off so many times. What should I do? For all the time I am spent trying to fix this damn mower I could have bought a new one.

    I had an identical problem and also thought it was the carb.

    I eventually took it to a repair shop, and he told me I had put too much oil in - he removed it, cleaned everything and it's now like brand new.

    If you have gas coming out of the carb (and especially gas coming out the exhaust) your carb's float is probably stuck down, or the float needle is stuck open. I suspect all it needs is a carb rebuild. Any small engine shop can rebuild it for you.
