Default Pinch Question

Im assuming if my piston will still push the sleeve up I still have pinch left. Am I correct to assume this. Thanks In advance.....

Yes it probably still has pinch. Don't worry about pinch so much, as long as it feels like it has compression when turning the flywheel. It should have a nice pop when it turns over.

I think it's funny that so many people are so concerned that they are losing pinch. The reality is, my engine will not run it's best until it's gone.

Now. If you can turn the shaft (without a clutch or flywheel) over with your finger easily with the glo plug installed?? Start worrying

really pinch, is not necesarily a good thing. It's still breaking in.

There are 2 forms of pinch the first is mechanical pinch. This is tested by how hard it is to turn the flywheel over, the second is compression pinch this is noted by the sound the engine makes when coming back down it should make a nice pop sound(varies) the mechanical tightness goes away over time but does not mean that you dont have compression.
