I have a Husqvarna 440e II that just has me stumped. (pun intended.) It will start after priming then cough and die, sometimes with a backfire. Everything points to fuel, or an air leak. I usually don't just throw parts at something, but I lost my *poop* trying to figure this one out. Here is what I have replaced, all with zero change:
New crank case gaskets and crank seals
New carb (twice) and intake boot
New fuel lines and filter
New primer bulb - it is priming beautifully
New cylinder and piston/ring
New coil
New magneto
Adjusting the China special carb did nothing, so I replaced it with a new OEM one and zero change in behavior. (My carb adjustment tool does not fit the new carb, but I highly doubt it's a carb adjustment.) I sprayed some starter fluid directly into the intake port with no carb or intake boot on at all, and it still didn't fire right up. I'm getting a beautiful spark. If I prime it, it will start and run for a few seconds, then just die. Exhaust port crystal clear, muffler clean. Ran the same with the muffler off. Absolutely baffled. The only thing i have not replaced is the crank and connecting rod assembly, but it seemed fine. Could it be geeked and throwing off the timing? Thoughts appreciated.
