Husqvarna 385xp mystery backfire

[Gord404]

a nice burst of flame and a backfire, pulled the flywheel and it had a sheared key, put a good one on its place and ran great- I have built and fixed hundreds of saws including 385 and 390,s so I have lots of parts and if it is your timing will be off causing it to fire at the wrong time or not at all- just trying to help-up to you what you do

I will pull the flywheel and see if it sheared. Thanks

If swapping the coil fixed it then that would've been it (Gord may have missed that post)
