Chrysler 135 compression ?

[ULUZ2A6]

I have a 1979 Glastron CVX 16 with a Chrysler 135. I am putting a new starter on it tonight in order to do a compression test. What kind of numbers are acceptable for a cold (50 degree) engine?<br /><br />can be seen at: http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=2448239595

Re: Chrysler 135 compression ?

Actual numbers can vary greatly due to differences in guages, technique and conditions, ULUZ.<br /><br />Your base (average) could be as low as 90psi or as high as 150psi. Which doesn't matter.<br /><br />What does matter is that all cylinders fall within 10%-15% of all others.<br /><br />Good luck.

Thank you. It was only 24 degrees when I did the test. All were at 115 psi equally.<br /><br />(EDIT: SORRY ULUZ, OFFERS TO SELL NOT ALLOWED. iboats does the engine selling here. JB)

One more question.<br /><br />What is the oil to fuel ratio for this engine? I have no owners manual. Please excuse my ignorance, as I am not a boat man.
