Dennis,

Unplugging the retard hose makes the engine race, and the "suck test" of the
advance makes it race also. You can also see the rotor move when you suck on
them with the cap off. The centrifugal advance is working at least in that
the timing mark moves to the left at higher rpms.

This is all pretty rough testing, though, and anything more precise is hard
to imagine testing. I mean where should the advance be at 3000rpm under such
and such a load? And so forth. I put on a rebuilt distributor but who's to
say what the spring tensions are?

Is it a good idea to lube the cent. advance assembly on a rebuilt dist.? I
didn't want to get oil in the Hall unit.
