Thanks for those photos Dave. Now I can see what might need to be done. Looks like I'll need to find someone with a broken supercharger and just swap out the entire face plate piece with the guts . . . That will also give me an excuse to change the jet oil in there too.

I've got an e-mail in to Rob at Needswings to see what assistance he might be able to offer . . . I should probably e-mail Rudy too and see if he has the parts I need.
