Hi,although you have done all that it still sounds to me like you have a carb problem,one cylinder is obviously not getting enough fuel,the difference between right and wrong when you are balancing carbs is less than 1/100th of a turn on the adjusters,you have to be very precise,also did you check that the mixtures were set corectly before you tried to balance the carbs,hope this helps...cheers

Just rebuilt carb, runs OK but needs some adjusting. where should start?


Sometimes hesitation means a vacuum leak. Check all hoses to the carburetor and also cap any unused connection tabs. The cap is usually a small rubber cap that slips over a tab.

Along with the vacuume leaks I would check the carb. The accelerator pump might be out of adjustment or something else in the carb. Currently I have the same problem with mine and I just adjusted it and for 1 day so far it's ran fine but I have a holley on mine. Carb may be dirty also.

Bike will not idle long pops on acceleration


Your bike has 4 carbs and they are not in sync with each other. This requires hooking a gauge to each carb individual and adjust till each one is exactly the same as the next. The imbalance can be from mis adjustment of just dirty carbs. You will also have balance problems if any cylinder gets lower compression.

Car hesitation from take off


No idea what car it is or the year..
It could be that the carb is needing to be cleaned and/or adjusted for fuel/air mixture..
Good plugs & wires is also a good idea..
Could also be a fuel pump or filter issue..
Could also be a vacuum or pvc valve issue..
Several things can cause a hesitation..

Havin trouble adjusting carburator for a 78 regal 3.8L, just runs a little rich and cant seem to adjust to correct specs at least close enough.


Warm up the automobile to operating temperature then use a vacuum Gauge attached to the intake manifold (not the carb).  Turn the idle adjustment screw "IN" until the car is about to cut out then turn the screw "OUT" 2-2 1/2 turns.  Look at the vacuum gauge if the gauge is steady at 18-22 then you are fine where you are at.  If not adjust 1/8 turn in or out until needle on the gauge is steady.  BTW the car has to be warm and You NEED the vacuum gauge....  Autozone or Shucks has one for loan so you have no excuse not to use one.  DO NOT over-tighten the adjustment screw if you do you can/will break off the tip in the metering passageway and then the carb has to be rebuilt or replaced.(  Yes this can and will happen and you can't just replace the crew.)
