I decided to replace the gas line and filter and got the same result. I should add that I replaced the primer bulb and it is working fine. I should also add that once the engine quits it is very hard to start again. The unit is about 3 years old but didn't get much use last year. I had to run it on half choke last year and the year before but now it runs on open. I have found the engine flooded several times. Is there a chance that when I move the engine from pointed down to up that somehow the engine becomes flooded? FIXED! While I was typing I was thinking about the engine flooding and if fuel was going in but not coming out maybe it had something to do with the muffler so I removed the spark arrestor screen and what would happen is that smoke would come out when I raised the engine but after about 5 minutes of lowering and raising the engine it really took off. It now works better than ever. I decided to replace the gas line and filter and got the same result. I should add that I replaced the primer bulb and it is working fine.
