Tuning a Proform/Holley carb, what parts and tools?

No, choke and idle issues have been resolved.

I'm down to either too much play up and down on the distributor shaft, coil going out, or fuel pump going out.
Weather here is no good for test runs, gonna try and get some tomorrow.

Anybody care to explain how to properly test the coil with a multimeter?

Where do I get the bushings for eliminating up/down play on distrbutor shaft? Doesn't Richard Ehrenburg sell some?

As for the fuel pump, probably just run a guage up to the windshield and have a buddy watch it, if I can figure out a good way to route the hose. How have you guys done it?
