Compression test results

With out knowing alot of your engine stats I would say the total may be slightly high but that aint causing your issue. I would back it down to 34* total, pretty common. Im still thinking a fuel related problem, keep digg'n.
My 340 would flutter and skip with the stock fuel pump. An Edelbrock hi volume pump cured that.
Brand new carb, fuel lines, pump, thing feels super responsive
