I have already changed rods for a step richer. Speaking of the carb, drove it last night wot and my idle was 1200rpm in park. The secondaries were cracked open a hair but could manually push the linkage back to shut them. Should the secondarys be cracked open normally?
You need to adjust/center the secondary butterflies so they don't hang up when closing. Idle mixture screws do not have to be the same. Every dual plane engine I've owned needed split jetting to even the burn.
