I like the curve but that is one hell of flat spot from 3600-4200RPM.
The run was actually started at 3500rpm when I mashed the throttle. The accelerator pump is a little too strong I think, which made it go way rich at first. Too bad the A/F curve wasn't printed out too.
I plan to keep it above 4400 as much as possible anyway. My gearing graph indicates that this will be no problem.
Gary, since I don't have EFI with O2 sensor feedback and/or anti knock sensing it's important to me to stay somewhat rich of max power. Much safer that way. And - what Geoff said.
Since one air correction jet size was enough to make a whole point of a/f difference I may ream an in between size to dial it in even closer. I rely on exhaust gas temps on track to make final adjustments.
Jake, yup. I used .080" shims under the rocker stands and still had to cut away a lot from the rockers for the swivel feet to clear.
