My ATC200M has a loud clunking noise when you turn it over with the electric starter. It sounds like it's coming from the bottom end. All the starter gears are good though. The starter is good. The soelonoid is good. It wolt start at all with the pull start either. The timing is right and is getting good spark. Any help I would appreciate.
Thanks

 

Arrrrgggggghhhhh. It's hard to diagnose over the internet, but if I had to guess, I'd say probably the crankshaft bearings. Unless it only happens when you try the electric starter. If it sounds like metal grinding, tear it down.
