Thanks to all of you for the warm welcome! We are working on figuring out a way to post some pictures so you can all see her.

Thanks for the tips on diagnosing the two speed vacuum diaphragm. I have checked the soft lines in the engine compartment and there is a metal vacuum block that I assume is the switching valve. It appears to have one good connection on it but the other is plugged and a line is laying below it with a bolt hose clamped to it. Is the switching valve a two way vacuum selector or is the diaphragm on the diff spring loaded to a default position and the vacuum pulls it off?

I guess I am still moderated so I have limited capabilities and can't IM or look up your email addresses.

The starter seems to get stuck and you have to tap on it to get it to crank. The previous owner put a new starter contactor on it and the battery seems a bit weak. What do you recommend for 6 volt batteries? Optima perhaps? Right now it won't start without a boost.

The next item I need to get to is the large exhaust leak. There is either a crack in the exhaust manifold or missing gasket under the intake manifold in addition it looks like the heat riser flapper holes have really worn. The flapper moves easy but you can wiggle the end shafts quite a bit. When it is running though the exhaust pulses seem squirt out of the area where the exhaust and
Intake manifolds meet under the carb. Any ideas before I pull it apart?

When is the big meeting in September? That sounds fun.

Thanks again for the hospitality.
