What really matters is that all the cylinders are within 10% of each other, so if you pull 150 from #1, hopefully the rest fall between 135 and 165. Remove all the spark plugs, disconnect coil wire, fix throttle wide open and give each cylinder a dry comp test, then squirt a little motor oil in each cylinder and retest for a wet test.
