Ted, one possibility is ignition timing. Your initial timing should be 24 BTDC, then there is no advance until the mechanical advance picks up at 4000 RPM. If your initial timing is retarded, it may not have enough advance to run well once it hits 3000 RPM, but when the mechanical advance starts it moves it enough to run better. Worth a check anyway.  <<Date: Sat, 6 Jun 2015 17:45:38 -0500

I've got a 1965 180 which I'm having an issue with and I need some advice.

>From about 3k - 4k rpm, the engine starts coughing and has a difficult time
gaining speed. This happens in every gear and if I can get beyond 4k, the
acceleration picks up again in most cases.

It seems like it is either not getting enough gas or is getting too much.

I'm thinking I may need a carb rebuild, but I wanted to get other opinions
