Re: Nothing but problems
Oh boy.. Sounds like an accelerator pump problem, but given you had the carbs apart, could be a number of things - jets, needle valve (and height) come to mind. Doesn't sound float level related (that usually is either too lean or too rich).
The accelerator pumps (there's one on each carb) overcome a problem that happens when you first crack the carb open. Carbs work off the Venturi effect - a low pressure area is created by the throat of the carb being constricted, which in turn causes fuel to bleed in from the float bowls, metered through the jet, and mixed with the incoming air inside the carb's throat.
When you first crack the throttle open, there isn't enough low pressure to "instantly" pull fuel into the airflow.. Thus, the accerlator pump was added - when you open the carbs, the pump squirts a small amount of fuel into the carb, achieving the same effect mechanically.. For sure your linkage attaches to it on the outside of the carb somewhere (and as I don't know your motor or have a manual, I can't get specific).
This is the place I'd start.. I would make sure all the accel pumps are all hooked up via the linkage and working properly. I would also make sure that when you crack the throttle open, you see a small amount of fuel being pushed into the carb (I don't know where the pump injects the fuel into your carbs - usually there's a small hole from the pump to the carb's throat).
