Question and Answers

Q:

My Craftsman rider has gas in oil system. Where do I start? I drained the oil and it is full of gas.

A:

Thank you for your question.

I am sorry you are having problems with your tractor. If the float in the carburetor dose not stop the flow of gas to the carburetor it will eventually fill the crankcase with gas. Debris stuck in the needle and seat is usually the cause of this problem. I recommend replacing all of the file line and the fuel filter. Then take the float of the bottom of the carburetor. Remove the hinge pin from the float. Make sure to hold on to the float it will fall out with the needle. Then remove the fuel line from the carburetor and spray carburetor cleaner into the hole the needle came out. This should flush out any debris stuck in the seat. After it is flushed out, the carburetor can be reassembled.

Before attempting to start the engine, make sure to drain the oil and remove the spark plug. Then hold a paper towel over the spark plug hole and turn the key to the start position. Let the engine turn over a few times. This should clear any gas in the cylinder. Let the engine sit over night to allow the gas to evaporate. The next day you can reinstall the spark plug, refill the engine with oil, and check the operation.

I hope this is helpful. Please let me know if you need further assistance.
