Its our old beater 2011 21 inch pusher used for trimming the horrid places ect and it died for no reason besides changing the oil and removing the blade to sharpen it. It ran fine 15 minutes earlier and has been used recently. So when I put it back running it just kicks and backfires through the muffler every time I pull it enough to get it to kick. Hasn’t been run into anything since yesterdays use so I don’t see how the flywheel key could be suddenly sheared. All it does it cough and snatch the cord now.
I did have i upside down for a while and I assume that some oil must have been left up in there and it got up top. When I pulled the plug it was dry as a bone, fired ok outside the engine ect and the mower turned over freely with it out. I did. Flush the piston top out with carb cleaner an yanked i over sending everything flying out the hole. I then blew i out with air and it all sailed out the exhaust.
So based on all that I sort of ran ou of ideas. What next, thanks..........
