Eddy, supposedly this sealer is not affected by alcohol. They used to advertise that it was the only sealer approved for aircraft use but I don't see it on the description anymore. I don't think I'd want to operate an airplane with a gas tank that a sealer had to be used on.

I've had to replace an air tank on my '56 and '59. I would think a new tank would be sealed. Not sure how you would thoroughly clean and seal an old tank, I guess it could be cleaned with acid, rinsed and sealed.

Thanks to Fred Dyke and Tad I found my governor on the firewall (I thought it would be on the compressor). I took the cover off and it seems to be free. I took the air lines off of the compressor and ran the engine and there was nothing, not even an attempt to make air, so as soon as I can I'll be taking the top off the compressor to see what's what. I'm thinking Tony may be right about the reed valves not seating. Thanks for all the help so far.

I'm very pleased with the engine so far, it starts right up on the 2nd turn of the starter and idles right away. I don't see any smoke either.

Tony Bullard, is that a Hall Scott 590 in that Autocar C100?

Jeff,I'm still running a couple of those kidney shaped governors,they are adjustable,be carefull of the copper finger in the housing it is filled with an expanding gas of some sort, don't horse with it,just the set screw and stop at the other end.

Hamish that's the 935-G1, 294 HP @ 2400. It's a strong old beast with a really nice deep sound.

Looks like you are making some progress. Can't wait to get down there, so I can see it in the flesh.

Gas tanks, and air tanks.

The rust in between the tank, and the straps is where I've had trouble before.
Had air leaking, and couldn't hear where it was with engine running.
Wouldn't stay built up long enough to find it with engine off.
I'd say air up your tanks from your shop compressor to see if you have a leak.
One fuel tank was so rusty inside I finally had one end cut off. Sand blasted inside, and welded back together.
Been good ever since, but this new gas makes me wonder what is going to happen next.
Hope this helps.

Thanks Tony, beautiful old truck.

Tony, is that the same truck Ray Haluch showed at Springfield ?

I pulled the head off the air compressor this evening, the reed valves look ok but the unloader valve cross is still frozen. It almost looks like it could be hanging the unloader valves open, although that seems unlikely. In any event I'm going to free everything up and put it back together. I'll need a head gasket for the compressor, anyone know where I can get one ? Aaron says the compressor is a Bendix 7-1/4.
