Question and Answers

Q:

Lawn Tractor keeps stalling

A:

Next time the engine starts to die, loosen the fuel cap for ten seconds. If the engine smoothes out, I recommend replacing the fuel cap. The fuel cap has a vent that should allow air to replace the used fuel. If the vent is plugged, fuel will eventually stop flowing from the tank. The fuel filter and the fuel pump if your tractor has one could also cause the same issue.

If you do not think fuel is not the problem, you have to determine if the engine has spark. To check the engine for spark remove the spark plug wire and insert a screwdriver into the boot. Make sure to hold the handle of the screwdriver and position the exposed metal portion of the screwdriver close to something metal on the engine. A bolt head will work well. Then try to start the engine. You should see a spark from the screwdriver to the bolt head. This mean the coil is good. If you do not see a spark most likely the coil need to be replaced. If you see a spark the problem is most likely fuel related. I hope this is helpful.

If you need further assistance, please submit more details.

Q:

How does the bowl come off of the carburetor for a Craftsman (Kohler Engine) riding lawn mower?

A:

The bowl on the carburetor is held on by the electric fuel shut off solenoid. The solenoid goes through the bowl and screws into the main nozzle of the carburetor.

Remove the solenoid by disconnecting the wire and turning the solenoid counter clockwise. Use a wrench on the shoulder of the solenoid to turn it off and tighten it when you install it back.

Q:

What would cause a lot of gas to spit out the exhaust and sometimes it won’t spin over?

A:

The carburetor float and needle valve is likely sticking and causing the fuel to flood over into the cylinder or the solenoid is not shutting the fuel off to the carburetor when the engine is not running. When the cylinder is filled with liquid fuel the engine will not turn over because of the hydraulic effect. Liquids cannot be compressed.

The failure could be the float sticking in the open position or the solenoid is not shutting fuel off when the key is turned off. I agree in replacing the carburetor assembly although there are kits to rebuild it.

  • 12-757-03-S----8.86---CARB KIT
  • 12-757-33-S----60.23--SOL KIT
  • 12-757-37-S----7.12---BOWL KIT

I recommend calling a service technician to diagnose and repair your tractor.
