So, as discussed in a previous thread, I have been having a very strange popping through the carburetors, specifically, under partial throttle, or immediately after putting my foot down after an upshift.
It is certainly not a lean pop anymore. Under WOT in any gear, it will run fine and not pop. If I stay in a gear and let off and then hammer back down, it almost never spits.
I don't know how much power the car is supposed to have, but it doesn't feel very quick, even high up in the powerband.
Before I pulled the engine, the timing was set correctly. Tomorrow morning, I will re-adjust the valves and re-verify timing.
Also, the car will occasionally sound like it "drops" 1 or 2 cylinders at idle.
Could the rotor/cap be causing this issue?
For reference, 1971 142S B20B dual SU HIF6's D cam pierburg mechanical pump bosch distributor with vac advance. Points and dwell are set correctly, plugs are nice and tan as they should be.
