Re: compression
I believe a 2 Stroke motor must have a minimum compression rating of at least 100 to 125 pounds per square inch to operate properly.
I may be corrected on this. |

Re: compression
95 psi is low but the bottom line is that if you are happy with the performance then 95 is perfect. That little engine was never that great at climbing hills as it was designed for the fairly level playing fields of a golf course. A newly rebuild and run in engine will give you ~130 psi and cost you around $200 to do. It's your call but if you are generally happy with it I would be tempted to leave it alone.

If you have a deeply scarred piston wall, you may have to go over .25..and the question is how many times do you want to rebuild it, if this is it, and you could care less about what happens after, go ahead and bore the engine, put a larger jet in the carb and then put the small head back on and you will have a running little motor. |
