az1966

just had my 1966 200 ci motor rebuilt,,,,, cylinders 2 thru six all have approx 170 lbs. on the compression test,,, cylinder 1 has only 135 lbs. sounds like an issue to me,,, the mechanics ran a leak down test on all cylinders and they all came in at roughly the same numbers.... don't remember what they were,,,,what gives,,, is it because their two different kinda tests or what


thanks for any help or info
