Thanks for the info Rain! I do plan to use the machine - otherwise, what's the point of owning it? - and hubby noticed the wiring when we took the motor and light off. It doesn't look so great, so I may order a new light and motor to use and preserve the original light and motor for historical purposes. (Unless I could talk hubby or youngest son into rewiring it.)
I would like to download a service manual for it but I'm unsure which one would be best. I've looked at the manuals for the 15-90 and the 15-91 but neither are exact matches. Would you have a recommendation as to which manual would work best?
Is it unusual that this machine has no reverse? I'm wondering if that is what's "special" about it. It's no biggie to me, but I do wonder why someone would prefer a machine with no reverse.
Thanks again for the help. I truly appreciate it.
