Two weeks ago it sounded like there was a vapor lock issue with it. It was making the surging noises that I have come to associate with that and blew out the gas cap & it ran fine.
This week it started doing it again, but would run fine if you turned the choke up. Then it stalled out. Yesterday I tried mowing again with the choke about halfway. It stalled out after about 15-20 minutes. Now it won't start at all. We have cleaned the air filter and the gas cap. We took off the fuel filter (which had little to no gas in it) and blew out the line to the tank & the first line toward the engine. Now there is no gas in the filter at all after cranking the engine.
Any thoughts?
