I am finishing up the engine for the RAJO Lake Style Roadster project. Since the compression on the engine will be considerable, I'm inclined to run a 12V starter. Are there any modern gear drive options available or any options readily available that are easily adapted. The magneto ring has been removed as well as the flywheel magnets. I also understand the starter ring gear will need to be flipped to have the drive engage on the opposite side. Any and all information for a source would be appreciated.
"I also understand the starter ring gear will need to be flipped to have the drive engage on the opposite side."
You said "modern gear drive options". Yes, you'd probably need to flip the gear as you mentioned.
Yes. I need more torque than a standard starter.
I'm trying to think whether turning the ring gear around accomplishes what you are after (getting the lead-in correct). I'll have to go and look at the gear.
I assume you still have oil flying around by the starter?
A flathead V8 starter might give you the torque you need on 6 volts and easier to seal/reduce the oil leaks than any new style starter. Consider that the spring and bendix are still on the back. I haven't tried it, just thinking
