Mine did exactly the same, especially when engine was cold. The cure is to put a small clamp on the flexible pipe, and adjust until the needle is smooth, but still reacts quickly to throttle changes. The problem is finding a small enough clamp! If you use a fairly flexible connecting tube you may get away with using a tie-wrap, gradually tightening it until the needle smoothes out.
