I really never thought about checking grounds and making sure it wasn't electrical. The stat sheet I got back on the carbs shows that it has 88 jets squared on both carbs. But I haven't taken a bowl off to verify, I guess that would be a good idea. But you would think they would flow the carbs after they changed them and make sure they fit the specs right?? I don't have another ignition box to try without pulling one out of another car or changing some wiring around but it may come down to that. Keep the ideas coming....
