replaced oil for a heavier one (castrol 20W50) but symptoms are still the same. again it was not like sitting in the garage over winter and now trying to start it, it was running and suddenly stopped so carb is quite unlikely. Spark is OK too, although I am using regular car spark plug as the original old one just cracked in half and I don't have original replacement (champion sells totally different sprak plug for this mover, and with this spark plug the engine does not run too)

Replacing piston rings is what I am going to do (at least the lowest one).

Have one more question - are piston rings pretty much the same for bs engines or are really model specific? JOhn deere sells such parts only thru dealers, and the closest one is 6000 miles west, so I will have to use whatever I will find on ebay
