You would thing that OS would send the new needle valve assy. to all registered owners of the "old" .91. They have made enough money from us.

I recently bought my first OS, a .46LA, it has the new needle assembly and works perfectly. Also, you fellas that have the problematic .91s can replace the needles with a MDS remote needle, they stand up to crankcase pressure when using a Cline regulator and do not leak. And they have nice secure bracket that goes on two of the backplate bolts. That's only one of many sources of remote needles available.
