Default Motor questions

I took out my truck today and was playing around with the flywheel. I have a mt with .50 motor. I was able to turn the flywheel pretty easily and have the piston go through the up and down cycle. It seems like the engine doesn't have any pinch left, is this correct ? If this is the case, do I need a new piston and sleeve ? This is my first vehicle and only has about a 1/2 gallon of 20 trinity monster horsepower through it. I'm thinking I may have run it hot to loose the pinch so fast. Is it okay to try and start it or will I do more damage trying to start it and run it the way it is ? Any help is greatly apprecieated

try resetting the needles back to factory setting and retune from there.. see what happens? if its hard to start after its been run a while might be time for a new P/S

Having no pinch left does not mean the motor is shot, as long as it has compression left that's all that really matters.
