I did some messing with stuff last night and think I have found the problem. The rod ends on the linkage bewteen the two carbs is very tight. The balls do not move nice and free in the ends at all. Looks like a good system but not very smooth, gives a ratchety feeling when you try and open the carbs slowly. So I either need to find a way to loosen the balls up or just make my own linkage.

Oh I also found out what the carbs are, not what I was told originally they were going to be They are 1804 Thunber Series AVS 500cfm .
