Rick,
Thanks for the "heads up". I've got copies of the Work shop Manual and Illustrated Parts List, thanks to Brian Asbury. Steep learning curve, but time in the garage has to be the best therapy available. Couldn't help but compare the original generator to a NOS spare that I inherited from Giorgio. Pulley swap and I should be in the running. Just wonder what year it will be when I start putting it back together. I welcome all the advice that I've been receiving, from welding to electrical.
