My 1936 85 HP has compression of 75-78 across the board. It runs fine, does not smoke or use oil. Can I correct the low compression by just replaceing the valves? Thanks Guys! TIM CARLIG

If it runs fine, doesn't smoke or burn oil, why would you want to touch it? "If it aint broke--don't fix it" Seriously, those numbers sound about right for a used motor. How many miles are on it? Why are you concerned?

Did you do the compression test with the carb throttle plates wide open?

96,000 miles, no...not with the throttle plates wide open. TIM CARLIG

Try a compression test with the engine warm, the throttle plates held open and all the spark plugs out. Probably will look much better. You could squirt some oil in each cylnder and run another test to gauge condition of rings. Regardless, the good part is, all pressures are very close to each other. Probably no problem.
