Anyone know what the compression should be on this engine. It's surprising how hard it can be to find info on these old engines. Thanks

This is a general statement ! As I do not know about your specific motor. Anything over 120lbs is great in my book.
I dont get concerned about compression until I see readings approaching 105. I know some maunfactures do not give specific #s. They do indicate that the readings should be even or close.

I got 124, 125, and 130. I know these are fine, just curious what they should be. Thanks
