"Bill they are an easy motor to rebuild, keep posting what you see and find as to why the motor did what it did...It could have seized due to over heating??

"well I took off the carb and seen that I was getting some leaking around the reeds so I took them off and cleaned them and sprayed some eng cleaner and let sit over night now put back together and seem to be getting more compression and a caugh from the motor but still no start. I have spark. should I still change out the rings. how much would I be looking at for new rings, thanks All"
 
"I would take it apart, check

"I would take it apart, check the condition of the cylinders and rings. Remove the rings, (hopefully they are not broken) they may just be gummed up and stuck within the groves and not sealing properly. I have had success with just freeing the rings (remove, clean grove and replace), light hone on the cylinder and putting it back together. Have not done this on bigger engines, but the small ones less than 10 hp I have done so quite a few times.

Have a great day

Rob."

Before doing anything..... sim

Before doing anything..... simply remove the cylinder head in order to inspect the head gasket. It's possible that the heasd wasn't torqued properly and the gasket failed between the two cylinders.
