I think, no I KNOW, that this thread is getting too anal. Please leave the throttle shafts ALONE. It is very unlikely that the throttle shafts are twisted. But if they are, it is the result of over torquing the throttle shaft nuts as previously pointed out.

A difference of one unit between the the two barrels is perfectly acceptable and should not be considered a fault that needs correction. Not in the carb anyway. A greater difference such as 3 or 4 units is a different story. But even then it's more likely that the fault lies in the engine than in the carb. In that case it IS more logical to check out the carb first before engine disassembly just to eliminate that rare chance that the carb shaft is twisted. With the removed from the manifold it will only take a visual examination to see if both butterflies are shut or open the same amount. Try that before you go twisting the throttle shafts on purpose by over torquing the nuts.
