Title: Ac1 conversion
Post by: Waxel on May 02, 2022, 04:17:48 PM
Hi, i have an ac1 generator with manual start handle. I'd like to covert this to electric start but would need to replace the flywheel with a toothed one. Has anyone done this or know availability of toothed flywheels? Thanks

The other option would be to buy a starter ring and machine flywheel. That is unless the flywheel has already  been machined to take the ring. I can't remember for sure if all flywheels were machined or not.

There's always the old golf cart starter/generator option.
Cheers

Don't know what part of the world you are in but currently on US EBay there is a listing with two AC1 electric start engines for $300

I have a starter motor that should fit. The flywheel is currently smooth. Am concerned that if I machine the flywheel it might cause it to become unbalanced

Hi, not sure what you mean by this?

@ Waxel
Use the search function to enter "starter/generator", you'll find a lot of links.
Veggie got me inspired to install one  on my 6/1, it works very well, and has for several years of regular use.
No reason it would not work for your engine.
Some examples

You can find golf cart starter/generators on ebay or maybe locally.

Thanks for the suggestions. Much as I love projects, I've already got a list ahead of me that is frightening. Also all the belts and pulleys look a bit deadly to fingers and doggies tails. I'm able to start my ac1 with the manual handle but the wife isn't so a simple starter motor option is all im looking for at this stage.  Maybe even with a 240v battery charger to keep the battery alive... am in Ireland and don't see any cheap electric start ac1s listed anywhere...

Amazingly, have just seen a toothed flywheel on ebay. Does anyone know how difficult replacing a flywheel might be?

That turned out to be a gear wheel of 15cm that I imagine is for engaging with starter handle. Have been quoted €200 for a 20" gear wheel that could apparently be fitted to the flywheel. It's expensive I think and don't even see how it would fit
