compression number veries from motor to motor, either it hot or cold, and if the throttle is open or not. what you should be looking for isconsistancy between the cylinder. if all of your compression are within 10 percent of each other, then are are fine. if you feel the compression are a little low, do a cylinder leak down test. when i did my compression test on my a2 cold motor by jumping the starter, i got from 185 to 200. which is fine.
