My motor seems to run ruff from just above idle to 1500 to 2000 rpm, above that runs great. Starts great as well.
I just put 6 new carb. Kits omcParts. Floats and all. New plugs and still having this problem.
So when I go to throttle up it runs kinda ruff but once I exceed around 1500-2000 it purrs.

Just checked compression have 100 psi on all 6 cyl. And 7/16 spark.
But I just seen that on the throttle arm thing there is a rubber clear small piece of those held on by oring that is bad and moves up when throttling. Therefore leave a small gap between arm and roller.
