That's just it, there is no noticeable loss of power or momentum, just a hard half second hiccup.

Can you be more specific on what I should be looking for? What would cause the secondaries to COMPLETELY drop out for a split second in a straight line under full throttle? Its not like a cylinder miss, its a complete carb backfire.

I've been kicking around the idea of installing an "in dash" wide band. It's not only great for dialing in the carb(s); it's the shiznit for troubleshooting too.
Just to rule that out Dave I just added a new cap, and rotor and plugs. It only does it with this carb, not the Demon so its gotta be carb-related. I do like the idea of an AF gauge in the cockpit. Been thinking about it in a fold-down panel that I can hide up under the dash. (Dont want this thing looking all new-school and stuff. )
