Much like machinists do on the crankshaft counter weights, I've drilled holes in the counter weights of a Carter AFB. I drilled too much out and then stuffed lead fishing weights in the holes to get it dialed in. It worked very nicely.

Getting the correct jet size, metering rods, vacuum plunger springs and accelerator pump discharge nozzels first is critical to success. I had to drill out the accelerator pump discharge nozzels to get one big enough.
