  1. Outdoors What is the easiet way to know that the piston is top center ? When I have my spark plug out and the piston is as close to the plug whole as possible, is that when the piston is at the top center point?

  2. Outdoors I have a lawn tractor 917.273380...it will start and mow for about 10 minutes then lose power and eventually shut down. I have adjusted the valves and it repeats the problem. I noticed the last time before adjusting that the top rocker arm is not moving in or out. What is the problem ? Thanks !
