Rebuilt this HS50 and it starts & runs good for around 5 minutes then shuts off while adjusting carb. When I try to restart it won't start after many pulls, check for spark, no spark. Take flywheel off and key is sheared in half. This has happened 3 times now with new genuine TEC keys. Not sure if shuts off because I'm trying to adj carb or the key shears while running? Also not sure if shearing of key is from many pulls trying to start after it shuts off.
Any ideas what it could be?
Thanks for the help.
