engine quesions

Lots of variables on an older motor, but look for compression no lower than 120 on a motor still tight enough to run well...Vac. depends on cam, but a stock set up should be 15 or more inches merc. and steady if no leaks...

Thanks! I am getting a very steady 19 on the vacuum gauge. I may just wait on the rebuild I was thinking about as long as the compression seems good. It was lower but some small carb adjustments brought it up and smoothed it out.
