Plumbing Questions
While waiting for the brass blacking solution, I thought I might work on the cockpit subassemblies. Can any of you historians help me with a problem with the kit-plumbing diagram? What is a pulsometer? In the reference pictures I have and the diagram here it looks like a sight gauge. In the diagram the oil goes from the tank to an oil pump then to this gauge when it seems more logical it would go to the mixture control (I plan a break at the X and a line to the mixture cylinder.)
The diagram also shows the gas line from the selector switch to a filter then on to the carburetor. Actually I think the filter outlet should go to the mixture control, mix with castor oil and then on to the carburetor. Instead the kit suggests a closed loop from the bottom of the mixture control cylinder back to the mixture control handle.
Interesting hand pump circuit. Looks like the hand pump is to empty residual fuel and oil in the bottom of the engine back to the main tank. If that is correct it shows how crude the technology was then. A flying bomb.
