Chain saw starts and idels for 1-2 minutes then backfires and dies if any throutel is given it backfires and dies instently
Check your spark plug for 'whiskering' (tiny strands of carbon collecting across electrodes) and clean and re-gap. If this not the problem, check carburettor fixing to engine - may be drawing air through failed sealing gasket. Good luck!

My Husky 36 did this. The oil pump drive gear was stripped and had to be replace. It's located under the flywheel/sprocket so you have to pull that. I couldn't find info on how to do that so had a local shop repair it for $70! Parts are cheap, labor is not.

hi cindilou50
check the oil filter from the oil tank,the oil line ,the worm gear and the oiler under the clutch.Clean the ways where the oil goes with compresed air.(after you fill out the oil tank)Also check the oil hose.

Pull off the exhaust, does the piston look ok?
If scored thats not good.
If ok check fuel filter , pressure test lines or remove and check for cracks. Just a start but check easy stuff 1st or get back to me with more info, cheers

two things could be happening.......first is vapor lock......make sure you breather tube is clear and working........next is ....it could have a bad ignition coil on it.....after the coil gets hot the spark can become irratic or just not work any more.....

This happens for two reasons. First of all, take off the chain and the bar and clean it all up as saw dust may be the culprit. The other reason is that some chain oils are too thick. you can thin it down a little bit by adding a little kerosene or gasoline.
