Hey Guys, Thanks for all the comments and suggestions! [sm=thumbs_up.gif]
I was lucky enough to locate an O.S. Max H60F by way of a Want Ad on another site. The original owner tells me it's NIB, but it has some definite corrosion issues. He also had the correct muffler for this engine, NIP. I just did the PayPal thing tonight so I should have it in a week or two. I also have a line on a second one, so I may end up with two of these!
I'm pretty sure I can get the crankcase back to a like new appearance with an acid based cleaning solution. I was told some mag wheel cleaners have a mild acid in them. We also use a similar acid at work for cleaning aluminum, but it's probably stronger than the wheel cleaner. I'll try the milder stuff first to see how it works out.
