With this post my build of the Holt 75 is all but completed. The reason I say “all but” two of the spark plug wire with boot I ordered are on back order. Anyway I have made all of the parts for the distributor from the last page of the drawings by George Brinell.
The mount for the distributor can be rotated to adjust the timing while the engine is running. I rather like that. I am using a CDI ignition system with a hall sensor. The magnet for the hall sensor is located at the bottom of the distributor mount. A steel disk with 4 holes is attached to the shaft that drives the distributor. As the disk turns it exposes the magnet to the hall sensor through the hole in the disk triggering a spark. The base for the distributor cap is screwed onto the distributor base. It will rotate with the base when timing is adjusted. The rotor is secured to the shaft that drives the distributor. After adjusting the hall sensor to fire number one cylinder at 15 degrees BTDC the rotor was positioned on the shaft pointing at the number one cylinders terminal on the distributor cap.
While I wait for the spark plug wire I will probably start building a base for the engine and a box to carry it in. When the the parts arrive it will be time to see if it will start. Then take some pictures and make a video.
