SU 4 screw stumble ... is there a cure?

Posted October 28, 200321 yr

The carbs on my '71 are the original 4 screw dome tops. The car stumbles off the line unless I pull the choke most of the way out. Is there an easy cure for this problem? It does it tuned or not.

They must not be tuned right if it stumbles off the line.
