generator on a r2

does anyone have or know what the generator looks like on a r2 does it have a adjustable pully so you can slip the belt on this r2 came to me on about 4 skids of parts i have it running good but the next step is get the battery charging and yes it does have a starter.

Hi i have 4 R2s 2 came with electric start one had a generator. Ithink it was a delco did not work had no regulator. It looked like any other 6 volt unit. No it did not have a adjustable pully. Never looked in the book as to what was listed for it. I purchased a belt [one of the wide ones] and it appears to work ok. i run it with out the gen. most of the time just use a 12 volt to start it. If i can be any more help e mail of list.
