Primary jet
« on: October 28, 2010, 11:48:48 AM »
What would be a starting point for a single air bleed .086 & no rods?  Was thinking 65-67?

Those are very unique units, early style divorce choke with the single main airbleed design.

The factory set them up with 64 jets, nearly as I can remember.

I free up the APT system in the baseplate, and install 69 or 70 jets with a set of our custom primary tapered rods, and external APT screw.....Cliff

I'm going to use this for dirt track, so I didn't want to use pri. rods. I opened the MAB to .086. I'd like to get a baseline for pri. jet without the rods.

Maybe I should have left the MAB alone.

It's an indirect airbleed, so it will be OK.  I'd start around 62-65 for jetting, do some testing and see what it likes?.....Cliff
