I can think of one of 2 things:
1 - vacuum leak - does the car backfire when you let off the gas ? If
so you are running the engine lean with a vacuum leak which may not be
present at idle - PCV valve maybe ?
2 - Most likely you have a slightly blocked jet. Remove the jets from the
body, they are held in by a brass screw, which when removed will have the
attached to it. (Hard to describe without a picture !!!). When you remove
of the jets, you may notice that they are blocked. Blow through them and try
get them unblocked. (You may also want to clean out the main jets in the
bowl while you are at it)
The carb on my car used to do this regularly. Junk in the fuel tank would
its way to the carb and block the jets (all it needs is 1 piece of grit).
problem by installing 2 small fuel filters in the fuel line.
