Well, I'll be a goddamned...

It worked! I was most concerned about the JB Weld sticking to the Saranwrap but it popped right off. There are a few wrinkle marks, which I can fill, but it now fits perfectly. Just a little more sanding and trimming and it should be just right for reassembly. I also filled in the stripped overflow and will retap that. Hallelujah for JB Weld! Rednecks engineers rejoice! If Dennis Magri uses JB Weld in his Vincent motors, I think this isn't too bad. Finally I put the crankshaft oil seal in with gasket sealant to keep it in and hopefully keep it from leaking.
