Have a '62 beetle that was converted to. 12 volt. The engine is a 1500 with a 6 volt flywheel and starter. It's tired with many issues. I plan to replace this engine with a stock 40 horse 6 volt to look original. I found online a 12 starter with a 6 volt gear from Carcraft. Carcraft sell this starter using a self supported 6 volt gear and does not use a bushing. I think this can work except the generator, regulater, choke element would be replace with 12 volt. Is there anything I have missed? Your thoughts are appreciated.

Spark coil would need to be 12 volt.

Bug On!

Why change the starter? As long as the flywheel and starter are matching run it. Engine will kick over better with 12v.

The starter will still be 12 volts. It's the starter gear that has to be 6 volt to match the 6volt flywheel.on the 40 horse engine.

You can run a 6 volt starter on 12volts. If you already have an engine with a matching starter and flywheel, run it.

If the starter on your tired 1500 is good, no need to replace it.

Ok, the tired 1500 has the 6volt flywheel and starter. What I do not like about this is I am using 12 volts on that starter. When I turn the key to start the tired motor there is a loud gear cranking. I checked the ring gear and it's bang up purity bad. One time I had trouble starting this engine with all of it's issues the started got hot and would not engage and was dead. So I just pushed start to get me on my way. Maybe I am a puris and just want it sound like a stock starter. I converted my 66 bus to 12 volts with a 12 starter and flywheel. All is good.

Sharp 64, thanks for consitering the cost. I think it would be a wash compairing changing out all the light bulbs wiper motor, radio That is converting back to a 6 volt bug. If it's working don't fix it. Just replace the starter as aboved.

Who said anything about doing any of that? I still think you’re missing what I’m saying. I’m not a 6v Nazi. I’m all for keeping it 12v. I was just saying if your 6v starter motor was in good condition there is no reason to change it. People run 6v starters for years on cars converted to 12v.

I have been running a 6volt starter on 12volts for near thirty years. no problems doing that.

Bug on!
