I have a 1.7 running dual webers and it will surge a little while at idol. It only comes up a couple hundred rpms's and then right back down.I want to find what the problem is and make it right...Any ideas? Carbs loading up?

If compression dwell timing are right on and not moving, then leanness caused by bad carb adjustment or a vacuum leak

or a sticking advance in the dizzy. And I hate American Idol.

Thanks guys much appreciated.
