Title: 12V flywheel for old 1200cc Post by: Frodo on July 08, 2016, 08:12:49 am My '56 is converted to 12V with a 1641cc "F" engine in it. I'm planning to build a 1200cc with an Okrasa-kit for it.
The 1200cc is from the late 50ies with a solid generator-mount. Is there a 12V flywheel that will fit the old engine without too much modification? Appreciate any tips. Frode Title: Re: Post by: RichardinNZ on July 08, 2016, 08:23:40 am Is this what you need:

Your simplest option is to run the original 30-horse flywheel with a six volt starter (to match the flywheel) on 12 volts. Or get your 6v starter/solenoid rewound to suit 12v.

Yeah, that's what I'm going to do. Did it in the late eighties in my autocross days. Thanks for the reminder, KS.

I don't know of any off the shelf solutions.

If I remember correctly, the 6v starter motor will work if you swap the solenoid for a 12v. |
