sorry, another manual to electric start Q

i hope someone will be kind enough to help me.

Im having trouble identifying parts needed to fit an electric starter.

Cant find my engine in the lists
i know its an early 80s (white) ID is: F9.9AM 6G8UL
I think it has charging capabilities.

Is there another name for this engine?

I think i need a 6g8 81800 starter, relay and the stuff for putting it all together right?

But will i have to change the flywheel/rotor thingy also?
( posts about e start here on the forum got me thinking)

other parts also??
...guess it will start to get expensive...

Thanks!

The model number is either incomplete or it's possible a European sold motor at which case We would not have any information on it. If your flywheel has the ring gear then it would probably work.
