It starts to diesel when I shut it off about 1/3 the time. It rarely does it at 12*.

Plus I have run it at 15*, and could not get a meaningful change.

Right now the truck is down as I am swapping out the steering column, but I have made lots of head way when I opened up the secondary transfer slots.

I have added jet size to the primaries, and run rich at 2000 rpm. Or about 12.5 afr. Yet still a little lean at 3000rpm cruise, or 14.0 +- .3 afr.

If I floor it. The afr drops to 11.5-12 range, and I have full rpm again.
