Same results. Won't pull past 5200 RPM. Ignition is all new. Only thing I noted after the run was the timing after the run was at 40 deg advanced. Guess I did not reset it after I put on the MSD 6AL.Didn't make another run for various reasons.Carb is about all I have left to pick on. Plugs were right on or maybe a bit on the lean side if anything..Calling Compuflow in Medina this week for guidance.Any ideas?Akron Don Gallimore
