Small Engine Troubleshooting Problems? Ask a Mechanic Now.
Hi Jerry, my name is***** will be assisting you.
Can you tell me what engine you have on this machine? The model number that you have posted isn't a good number according to Snapper parts look up. I would suggest a new spark plug. The oil mixture running through the engine really shouldn't hurt anything else but it can foul the spark plug because of the oil. When you cleaned the carburetor did you clean the holes in the bolt/nut that holds the bowl on the bottom of the carburetor? If not I would thoroughly clean the holes that are in it.
Can you provide the engine information(model, type and serial/code numbers) so that I can better assist you?
It just sounds like there is a problem in the fuel system that is not allowing enough fuel to pass through the carburetor which will cause you to have to keep it partially choked in order to get it to run.
If you can tell me more information about the engine, what brand, style carburetor it has it would be helpful.
That makes me think bad sensor!
