I parting out a Bolens BL150 yesterday and looking for what had failed.
Customer he got it to run after putting some Seafoam in it but it quit.
No wonder after what I found upon my initial look see. The reed valve was damaged. Well pulling the crankcase cover I found a bent connecting rod and the crank pin was busted out the laminated crank. Now this wasn't the result of the root cause. This was that the piston rings locator (both of them) pins were completely worn away allowing the rings to rotate and catch on the transfer ports.
Just wondering has anyone ran into this? KInda a shame this happen to this Bolens as it had a chrome plated cylinder and only had minor damage. Nothing that would kill it cylinder wise.
