It probably needs a good cleaning. Take it off and get a can of chemtool spray (the stuff is awesome) and soak that ****** with it. Then take an air nozzle and blow it all clean,and reinstall.

My riding lawn mower won't stay 4unning unless it's on choke

Hi Rebecca, More likely you have a restricted jet in the carburetor. the only real solution is to take the carb apart and clean out all of the passageways.

The fuel jet in the carburetor is gummed up. You'll have to disassemble the carb to get to the jet. spray some carburetor cleaner with the small tube in the nozzle on the jet to clear the gummy build up

The mower will crank over and it will run for a few secounds and stop running why wont it stay running

If it runs for a short time on choke then cuts out it is because there is dirt in the carb jets, you need to remove the carb and clean the internall components.

Mower will only run in choke position

Partially obstructed main jet. Remove carb bowl and clean main jet with small strand of wire. Drain carb bowl and clean out any dirt or rust.

Good luck and be careful.

I have a troy built self propelled mower, it ran great last season, now it will not stay running. I checked to see if it was getting fuel and it is. I primed it and it acts like it is going to run and then...

The jets in carbs are really small and clog easily. If you stored your mower with gas in it start by replacing the gas. Remove the air filter and prime the carb. Start the engine and place your fingers over the air intake on the carb. This will cause the engine to stall as it will be starved for air. It will also create a powerful suction on the jets and possibly dislodge a blockage. Prime the engine again and start. If does not continue to run, repeat the steps again. If after 3-4 tries your engine wont run you will have to remove the carb and clean the jets manually. The reason your engine runs for a short time is because it is burning the fuel that you put in there by priming it. After that the fuel comes through the jets in the carb and if these jets are clogged the engine will die.
