I've been reading into this problem and i see that it might be the low oil sensor and such. I did unplug the yellow wire and it still does the same thing. It starts. It runs for a little but when i start pushing the blower around, it shuts off. I keep starting it, it runs, and eventually it runs, but at that point i want to throw it off a cliff. I have no idea what it could be. The sensor is unplugged (the single yellow wire) but it still gives me problems. I ran carb cleaner through it for a while thinking it was something along those lines and it worked for the remainder of the day that i needed it (20 min) THe spark plug is new. Fuel is clean. Its been doing this pretty much all season. Any ideas??
