Let me rephrase what I said earlier: the carb under the influence of the middle screw between the two has it's spring completely compressed and still cannot match the tightness of the other carb (the one under the influence of the idle screw) for a bench sync.
If I am understanding you correctly you want me to unscrew the two screws holding the butterfly in place, let it drop down and then realign it so that it is even within the frame. If I do this will I be able to match the tightness of the two carbs without the middle screw being completely compressed?
You're prescription would be to take the carbs apart again and re-measure the floats to the stock 18.5mm at an angle and proceed from there?
Also I found several problems today:
1. The carbs have started leaking fuel out of the breather tubes.
2. The fuel line has started to leak so I think I need tighter fitting line. Got some proper 5.5mm coming in the mail as we speak.
3. After taking the carbs apart again I noticed that the float bowl gaskets were not holding in place, so I have ordered new ones that will fit the shape without having to finagle them in and have them warp.
4. Battery wise the one I had been sold was bad so I exchanged that out at the store today for a fresh one, so that is no longer a factor either.
