1952 8BA. New Pistons, rings, wrist pins, has adjustable lifters. Was running fine. Started having a power problem and tapping sound. Also had occasional backfire through exhaust (not through carb) Suspected a stuck valve and ran a compression check.95-110 for cylinders 2-8, #1 was only 35 lbs. Opened the top up and valve operation looked OK, removed head and pulled Exhaust valve assembly. Lapped valve in case it was something not allowing the valve to close. Re assembled, adjusted both exhaust & intake valve. After assembling, disassembling and assembling again I am still hearing the sound and have no compression in #1. I enjoying chasing and solving the problems but would appreciate your input. Thanks
