Small Engine Troubleshooting Problems? Ask a Mechanic Now.
This is the 4 cycle engine? Rings are installed with end gaps 180 degrees from each other, position on piston is not important. If it was two cycle engine, the piston would have pins in the ring grooves to only let ring go in one position, to clear the intake and exhaust port.
I see question is still open, did you get my response?
