Hi Dr1

First I have been running this engine for 15 years with no nut, and I would be happy to put one on if I could match up the size and thread I know its metric but the gages I have don't match, or come close.

But I pulled the sleeve and cleaned the shaft and the inside dia and reinstalled it with fresh Green Loc-Tite So we will see next flying day.

And Thanks for your help

Cheers Bob T
