Hi Stan --

I'm wondering if you could give a bit more detailed description of what
the rebuilder did wrong?  I've rebuilt my air-cooled Type IV, and hope
never to do it again (I've gone diesel ;), but I'm still interested!

I get that the case is somehow snapped together wrong, but in what way,
and how did you detect it on disassembly?

Thanks!
