You need voltage at coil + to make spark. A 12V test light (or a meter) will tell whether you have voltage. The alternator won't put out anything until the engine is running.

I use an impact screwdriver to get them out. This is the type you tap with a hammer, not a power tool.

The pulley and shaft should have a key to keep them rotating together. The setscrew should just serve to keep the pulley from moving axially on the shaft. And yes, putting a divot in the shaft for...

A set screw is pretty standard for that application. I would have expected the old pulley to have been drilled for a set screw, but not necessarily the new one.

Seems you have two choices.
First is to drill and tap that manifold (1/8" NPT) for the scavenge tube. If you have a drill press you should be able to do it yourself. Or a machine shop could do it....

As I recall, my charge was a bit higher, the float a bit lower. But the modern regulators will let you change these parameters to suit the owner - I like that!

If you have glycol cooling, the HX should have a zinc in the raw water side.
