super 77 compression???

56oliver · Feb 27, 2015

Does anyone know how much compression should a super 77 have? Also, it is a gas tractor.

Thanks

Did you check the compression or are you thinking about making a compression test. Let me ask you this: Has your tractor been converted to 12 Volts. If you did the compression test, did you have the throttle all the way open and all six plugs out? Now I would be more concerned more how even the compression is between all 6 cylinders. Now you are probably thinking I am talking like a worthless political person. Answer me those questions and I will tell you what Oliver called for a minimum spec. If you have more variation than 10% I would make a cylinder leak down test. My 2 cents worth. J.

its original 6v system... I just wanted to do a compression test to make sure things are all good. It doesn't smoke or anything, I'm just curious. Thanks for the help

I haven't done a test but when I do should I leave all 6 plugs out or only the one I'm testing?

Leave them all out, throttle wide open. I will send you an e-mail. J.
