I think that Terrytuned may well be right. Assuming you are running on a 26VA carburettor, and assuming that it is in reasonable fettle, setting the mixture is not too difficult.
The method I use is to get the engine hot and set the throttle screw to a fairly brisk tickover. Wind the mixture screw on the top either in or out to get the engine running at its quickest. Reset the throttle screw to lower the tickover at little and then wind the mixture screw out until the tickover begins to drop. snap the throttle open about 1/4 of its travel and let it fall back.
If the engine revs dip and then come back up, then the mixture is too weak. wind the mixture screw in a tiny bit and repeat. When flicking the throttle results in the revs returning to an even tickover without it 'dipping', the mixture is correct.
Adjust the tickover to a sensible level (about 500 rpm or so) on the throttle screw. Don't be tempted to take the tickover too slow, otherwise the car will stall if the engine in either not up to temperature or hotter than normal.
Hope this helps!.
