I've got a 302/350 hp Engine Factory engine with a 650 Thunder Series AVS carb. From a stop or very slow speed, if you floor the pedal and run through the gears at max RPM, it just screams. If you are cruising between 1500 and 3000 rpm and you suddenly floor it, it bogs briefly and then takes off. I have adjusted the timing, made dizzy adjustments to bring in full advance earlier. Timing is at 16 degrees initial advance and around 40 degrees at 3000 rpm. No pinging on pump 91 octane fuel. Noticed ping at 42 degrees and backed off to 40. I went up to stronger metering rod springs and slightly smaller rods. Adjusted the secondaries to open under very light pressure. Still bogs from mid rpm flooring. Does it need to be richer or leaner to eliminate this condition. What do I change next to correct this condition?
