push, self-propelled, mulching mower. When starting, it turns over but doesn't remain running. Know it's not the spark plug, gas and oil in it, choke is pulled, but it doesn't seem to ...get fuel to keep it running??? It stalled on me previously and I cleaned the air filter, and that resolved the stalling initially, but now it just doesn't run...stay running. like I said, it turns over and runs for approximately 2 to 3 seconds.
