[Sharps40]

1 hour well spent.

Previously leaned down the main circuit at the bottom thru the midrange by going from 70 jet to 60....a 14.5%ish reduction in fuel flow for idle and transition. Runs great just like Mr. Langdon said it would....tuned it and drove it a day.....crisper across the RPM band on the main but slightly worse on the transition into the secondary.

The secondary, at the top of main, bottom of secondary still dropped into a lean hole when ya hammered it. Timing advance was not a help so set it back to 17 BTDC and thought it thru.

That 125 jet on the main, at the base of the emulsion tube, limits the total fuel running into the circuit, bottom to top. Swapped it out for the original 140 jet and retuned the emulsion flow and closed the lower butterfly a touch more....out for a drive.

Still very crisp on the main and you can hammer the secondary on in all gears with no hesitation. Got it out on the highway and same thing, ya can push hard in OD with only the tiniest surging up hill at WOT.

So, I think I have it 99%. Gotta drive it a week or so. May need a slightly larger main jet on the Secondary to make sure I continually to run richer in the top of the secondary all the way to WOT....should take out the surging but overall,......

A very productive half hour.
