Inliners International Forums Thread Like Summary - Misfire Problem

I'm having a problem with my 292 Chevy. After warming up, it misfires while holding a speed on level ground, when I accelerate, the miss goes away and it pulls very strong, level out at speed and the miss comes back and gets worse. Some info , the engine has about 3000 miles since a rebuild, it has a very small comp cam, offy 4 barrel intake, Clifford headers and points distributor. Everything ran fine until a couple months ago. any help would be greatly appreciated.

In my experience, if more throttle always makes it worse, it's electrical.
If it "cleans up" at some point, it's fuel delivery.
