Thanks as allways for the info (I have run the ST2300 for a few years with lots of success due to your page..)
But two minor requests. One the PN for the Pipe from Macs, and you just need to edit the first line a little to make referance to bearings,
1. OS 1.60 - after break in with a 17 x 12, needle should be about 1 1/4 to 1 1/8 open. Run the stock one until it gets rough; then replace it with the 2RS-SS6904 from Boca, or the same one from
www.afcbearings.com but it's the SS two rubber seal bearing. Replace it once, no after run needed, run dry at end of day, forget it. You will wear out before it does.
Just after the needle settings - just add that you are talking about the bearing problems they have. Only reason I know about it is We where discussing this at the field with the Dist 1 VP from NSRCA last week. Like I said thanks and I may be trying one in one of the two planes I hope to put together this winter.
