Thanks for explanation Terry. Back in my younger days I was a drag racer and used MSD ignition systems. With an MSD you always need a "load" if it was powered up and the engine turned over. Otherwise you'd fry it. I saw quite a few guys pull the coil wire and use the starter to turn over...

Hello, New to the forum and I just started looking at your thread. I love the mix of mechanical and electrical engineering. Could you explain how the Hall Sensor triggers the CDI. What is the purpose of the 2N2222?

Thanks for the response Chris. My idea was to get the engine running using a modern carb and then implement Henry's original design. Sounds like the carb was just too big for the engine. Sizing a carb can be tricky, too big and it will run too rich. Too small and it will run too lean which...

Hi Chris, would you be willing to share the information about the carb you are using. I'm starting on my build ( the engine first) and would like to procure a carb soon. Thanks for all the updates. Jim

Chris, I have to apologize for my earlier post regarding the ignition. I went back and re-read a lot of your posts and realized your are duplicating the original ignition system. So obviously most of my comments would not apply. Also, I did hear back from Dave Dunlavy and I now have the the...

Thanks, I have sent a message to Dave Dunlavy, but have not received a reply, I'll keep trying. While I've not built my engine yet, I have studied the ignition timing some and I've built quite a few engines (automotive) over the years. I don't know what you are using for an ignition system but...

Hello, I realize I'm rather late in joining this conversation, but I was wondering how to go about getting plans/drawings for the Quadricycle. I've been unable to figure out how to get the original George De Angelis plans or the plans developed for the New England Institute of Technology...
