Since it's easiest, I'd still pursue the fuel aspect. While running wfo and the engine is trying to die, use a squirt bottle with some premix in it and give the carb a little shot and notice what happens. If it picks up for just a second and then falls off, you've got a fuel delivery problem. If it falls on its face immediately (flooded) or has no effect, you've probably got an ignition problem. Give that a try and get back to us on this post and tell us what happens.<br /><br />g'luck & c/6<br />Hooty
