well, got the regulator in.

set it at 6 psi, and took it out for a drive. under full throttle it steadily dropped off until it leveled at about 2psi. that was about 5500, and by then it was breaking up. not falling off, but missing and breaking up, the problem i'm going after.

A/F mixture stayed the same, in the low to mid 12's, even when it was at 2psi.

now at first i thought that was a big deal, but since it actually had pressure, that means there was something that was resisting it, namely closed needles and seats. also, if it truly was unable to keep up with the demand, then it would have gone lean once the pump could no longer keep up can supply the engine with the gas it needed.

make sense? am i off base??

we are going to tackle the ignition next. we're going to put a points distributor back in and eliminate the entire ignition system and go from there.

someone mentioned a rocker arm. i just adjusted the valves, so i know that isn't an issue.
