The richening, Pbanders? Chris Foley? Dirty injectors? 2056 and a strange lean Options

I think we are there. This is fully warmed up after 20 miles on the interstate. Video is from the return trip home, vacuum advanced hooked up again. Running nice and cool, 72ish mph for the first half, then down to 55 a little after the middle. Still a hair rich at WOT but that is fine with me. Maybe I will screw in the full load stop a hair to compensate for moving in the outer screw. No bucking/lean misses.

Just took a look at my timing now that everything is running perfect. At 850 it's at 7.5 btdc and 27 at 3500. Of course that is all plus or minus whatever my marks are off. I turned back the outer screw almost a half of what I tightened it yesterday. Took it for a long drive. Was interesting, tried it with and without the advance and for once the advance made a marked improvement in smoothness of throttle response. I think everything is finally coming together.


I was asking myself about that timing technique for the d-jet .. after you put on a 123dizzy, is it really necessary to go with the 3500 or can you just use the low rpm timing? Anyone know why they had a different method for the d-jet?
