Anyone know what the ideal and acceptable range and variation (difference between cyclinders) of compression readings (hot and/or cold engine) are for a standard automotive type compression test on Rotax 912UL?
(Preferably in PSI)
And at what indicators/reading of pressure does one have either indicators of signficant wear or problems?
I waded through a lot of Rotax documentation and couldn't seem to find that info for the standard (non-leakdown) compression tests.
There was lots of info on using and interpreting the leakdown test.
Couldn't find much on the standard test, other than it is an alternate method.
I realize the leakdown compression test is preferable but not an option right now.
