  1. Sounds like you have an original coil. The "dial" or "knob" as you describe it is a ballast resistor for the coil. It keeps the coil from overheating when ignition is on for long periods without the engine running. The resistor should have a circular porcelain core with spiraled wire running around its circumference. You can test it with a continuity tester / ohm meter. If it has continuity, it's good. If not, that would explain why your coil is not firing. Perhaps the internal wire has rusted away.

     

     

  2. In addition to what has been mentioned, I would try substituting a coil from a newer vehicle such as a 1954 Chevrolet with a condenser on the negative lead and no resistor. The original coils are known to be unreliable. They have the condenser built-in and unless it has been taken apart, as in having the tar melted out and condenser replaced with a modern equivalent, it's definitely bad by now.

     

    Another question, do you have the carburetor intake hooked up to the pre-heater on the exhaust? These motors run best with warm air.

     

  3. The trick is never touch the silver on the reflectors. Any contaminates such as the natural oils in your skin will tarnish the silver. Do not use rubber-impregnated gaskets. The oils in the rubber will tarnish the silver too. Put on white museum gloves when handling them for installation. I have never used any products or done any cleaning on mine and they look as good as the day they were installed 18 years ago.

  4. I have had the Peterson regulator in both my cars for years with no problems. I kept the original cut-out and 3rd brush for max current regulation. I don't like to fully tax my generator in the event the battery goes flat. I was surprised by observing the ammeter just how fast a good battery recovers after starting the engine. By the time I reach the end of my street, the ammeter is already approaching zero.

  5. Those Optimas are like 800 CCA which is higher than most wet cell batteries. If you need two of them to crank your car, then you have other issues. Possibly bad starter, bad ground, or cable size too small. The power density of two 6-volt Optimas in parallel is probably too much for your poor little generator to keep up.

  6. The Superiors were from 1923 - 1926. Then in 1927 came Capitol and in 1928, National. 4-wheel brakes would put the chassis at 1928 since that was the first year for 4-wheel brakes. The radiator shell resembles a Capitol but the trucks were typically a year behind in styling so that could be National. The headlamps appear to be from a 6-cylinder and resemble 1931.

  7. The hot air pipe is simply a flexible metal tube that draws air from the air filter you pictured, around the outside of the exhaust pipe, and into the carburetor. It is routed behind the motor, above the starter, and into the carburetor. It is available as a reproduction part. The air filter you pictured is basically an empty tin can with louvers around the bottom. The idea is the vortex of air will spin any heavy debris out. I think the vortex was only in the designer's head.

  8. An all original 27 would have a Carter RX-0 or RAKX-0 carburetor and a vacuum tank for fuel delivery and not an electric pump. Assuming that is the case with your car, here are the things I would check in order of least difficulty. Does the carburetor still have the flex pipe from the exhaust pre-heater installed? The RX-0 carburetors like hot air. Without this pipe, the motor will be very cold-natured and tend to spit and pop from the carburetor when you touch the throttle. The only adjustment available to you would be the idle air screw. If it's idling properly, chances are it's adjusted ok. Also those carburetors have no accelerator pump so transition off the idle circuit takes some feathering of the throttle. Some hesitation is normal when you "give it the gas". Next thing I would do is disconnect the fuel line from the carburetor and make sure it has good flow. Then I'd drop the float bowl and check the float level as well as overall cleanliness. If the fuel system checks out, I would then look at the condition of the plugs, plug wires, check the ignition point gap, and timing.

     

    Cheers!
