When talking about shims, it is always reffered to the total amount of head clearance.
0.95 is to much, your engine probably doesn't have a lot of bottom power.....
Run the engine with an head clearance between 0.6 - 0.7mm
Measuring with solder is a possibility, I always do it this way. (if possible due to the engine's pinch)
Take out your plug, rotate the flywheel until your piston is in TDC.
Unscrew the engines head and burnroom.
Measure the distance between top of piston and top of liner.
Make the same measurement for your burnroom (without any shim)
Now you know the headclearance your engine has, without any shims installed.
(should be 0.55mm, concluded from your story)
Thanks alot for the explanation I got the picture now.What you say is true the engine does not have any bottom punch.I thought its the engine powerband that makes it like that.
Will go back and reshim my engine and see how it perform.Do you think its because of the engine head clearance at 0.95mm cause the con rod to fail in less than 1 gallon of fuel as I have posted it on this forum before.
