Gravely losing power under load

Price for rings I think is roughly $30 - $40 per cylinder. Labor would be what would get you. If it were me I'd charge a minimum of $200 - $250. Make sure that tank and lines are clean and that the fuel filter is ok. Cant remember if you said you replaced it or not lol. Make sure governor springs and levers aren't binding in no way. Sorry for so much info! Haha

Just to close the loop on this, turns out one of the ignition coils was bad. Thanks again for your insight and troubleshooting help!
