While checking for spark on the Wisconsin engine I thought I noticed puffs of air from the carb as it was turning over. I got my compression tester and stuck it in the plug hole. While holding it in tight with my left had I reached over and thurned the key with the right. Suddenly a loud pop and the tester flew out of my hand. The recovered tester showed about 60 lbs of compression. I know this engine has a compression release built in so would this be a normal reading, low or is it even an accurate way of checking?

With the compression release, I found a healthy engine normally reads 60-75 on the tester.
