More progress towards startup.
CRANKCASE VENTILATION: While I wanted to dress up the '47 engine with '40 attachments such as '40 oil filler tube (shorter), filler cap (finned), and oil bath air cleaner with bulbous shape at the carburetor (not flattened), the improvements to crankcase ventilation after 1940 are worth retaining on the '47. This includes the taller oil filler tube so that the cap would cap would catch more air from the fan, a change in the oil filler cap to a larger, flatter shape with a large slit on the forward side to catch more air, and later the addition of a tube to direct the air from the fan more forcefully and directly to the slit in the cap. I would imagine a diligent dealer making these upgrades to the '40 engine when it was brought in for servicing.
AIR CLEANER: The '40 oil bath air cleaner was not in great shape, but we blasted and painted it. When I get it home, I'll fill the surface, but at least it's the '40 design.
HEATER/DEFROSTER: The heater had been making dinging noises because the bearing was going. The core was shot and the water tubes constricted. These were replaced, so it should be toasty and quiet next time.
RADIATOR PIPE: In matching up a '40 radiator with a '47 engine, the spout at the front on the '40 has to be retained. The '47 spout points left. Also the long radiator pipe. John Kepich, who used to provide these pipes, sold his exhaust systems/pipe-making business, but the new owner hasn't set up much of the equipment yet. David Moe sent us several to try out. One was perfect in shape. We had it cleaned, filled and reinforced.
In preparing to start up, one of the inner manifold studs showed moister, so it was replaced. My son John used some kind of pressure pot to pump oil throughout the engine, especially the hydraulic lifters.
Yesterday John was ready to start the engine for the first time since it was rebuilt. The ignition key wouldn't turn the cylinder. Very frustrating. After a half hour trying everything plus other keys I'd given him, in desperation, I suggested he hit it (not hard) with a rubber mallet and try again. Bingo. But it didn't start immediately and it being late he decided to try it again later.
