OK, several days away from GSR here, so here's the update:
Yes, I tried rapping/tapping/cajoling the float into floating. The carb had at some point begun to drip instead of streaming out fuel. It continued to do that, though. My friend came over and found that he had installed something wrong with the float on that carb. The carb still drips when the bike is parked on the side stand, but seems not to when parked on the center stand. It's kind of a heavy machine to drag up onto the center stand, but I will deal with that for now.
I also found that the PO or somebody had incorrectly wired the white and black/yellow coil wires. After straightening out those wires and reinstalling the carbs, the 750 fired up without too much cranking. My friend stayed to do some adjustment on the carbs. It needs more, but it does run.
I need to go back into the ignition and do the relay trick now that I have a running bike, and also check valve lash. I looked through the Clymer manual and was both pleased and disappointed to learn that this engine has a direct acting valvetrain, just like my VW junk. I like the directness and the simplicity of design, but I do not like the need for shims, having been hoping on the Suzuki that it would be a matter of turning adjustment screws on rockers. Eh, oh well. I assume that the shims aren't too hard to get.
So, it is running and in time to be my transportation to school. And I can finally give my impressions of the bike, which are mostly positive. I like the overall feel of it. It feels slightly large for my height, 5' 10". My arms are a little too straight for my taste, but I can live with that. It feels very positive in spite of desparately needing the new fork seals installed and new tires front and rear. It feels easy to balance, is mechanically quieter than the Nighthawk I had last summer and has a very pleasing exhaust note. It seems to take a long time to warm up; I am ten minutes into my ride before it will idle off the choke. The brakes seem to be more than adequate, and I really like having a hydraulic rear disc brake compared to the cable-pulled drum on my Nighthawk, which seemed to require frequent adjustment. I like this bike a lot so far. It's a much better fit for me than the Nighthawk 650 ('83 model, 16V and shaft drive) or the scooters I had been riding more recently.
