Any body would like to share you experience? Thank you.

if you replace the Piston and Liner I would say very much of 100%, that is as long as the Crank Bearings/Bushing, Rod Bushings and Piston Rest Pin is in good shape too,

BTW, you want another 1, PM me

I would not worry to much if the pinch still exists at the TDC. As the engine warms up, it will expand and the clearance will not be a problem. Just make sure you have some Castor oil in your fuel and you are good to go.
