If you did, did you mike them or check them in any way? I can't see going thru one of these engine and not putting in new cylinders. That's the great thing about these engines. New cylinders equal new engine. Need more information as to what all you did to the engine. [Reply]  [No Email]

I assume the throttle was blocked open with good airflow and you had sufficient cranking RPM? I'd do a wet test next since your dry cranking is inconclusive. If your results are still down I'd do cylinder leakage to narrow down the problem. [Reply]  [No Email]

Approximately how many hours? Did you adjust the valve stem clearance between cam/lifter and valve after grinding valves? What clearance settings did you use there? [Reply]  [No Email]

And of course if you used the old sleeves and new rings did you measure so as to make sure the new rings would even fit right and have the correct end gap in the bore [Reply]  [No Email]
