I believe the cable bracket and spring attaches to the carb bolt at the back of the carb, did you look at the cable bracket and spring setup further down on the page?

look again at my 750 compared to my 600. you can clearly see that the 750 has a KD hole and a longer lever. the 600 DOES NOT have the same lever = NO KD hole.

i know the bracket you're talking about i know i need that one. my question is what to do about the fact that my throttle lever has no KD hole and why it doesn't.

Yup, I like that one too. (thanks 30Desoto )

I think you'll need to shop around for another parts carb ... at the auto wreckers or at a swap meet or something. You'll need to find a used carb that has the correct primary throttle shaft. You'll have to make sure that it has the same lower linkage as well as the same butterfly size.

I dunno, guy ... maybe you just plain need a different carb. Trade someone your double-pumper for a vaccuum-secondary carb with the correct linkage? As I mentioned earlier, popular opinion says a VS carb is better suited to an automatic. You CAN buy a "trick kit" containing a selection of secondary springs, so that you can "tailor" the opening rate of the secondaries.

My experience (with a 3310 -- 750/780 cfm on a 351C Ford) was that the purple spring was the "ticket". The secondaries were coming in at around 2500 RPM and were fully open by about 3200 ... right in the power band.

I had originally been running an 1850 (600 cfm) with the default black spring. The secondaries didn't open until around 4500 -- even with that smaller carb -- and it was crying for more air/fuel! You could sure feel it when they finally opened though!

To top it all off (if this is a street mchine) I'd almost guarantee you that you'll get better mileage with ONE accelerator pump rather than TWO. Less bog, too, unless you're driving something real light with low gearing.

Good luck with whatever you decide.

I read this one AFTER posting my reply, and this is not meant to be a "smart guy" remark.

I honestly think the answer is that it doesn't have a KD hole because Holley felt that this carb was not designed for an automatic.

yeah, i've pretty much succumbed to the conclusion that this is a man trany carb for a reason. i'm gonna trade it for a VS. this has only been an exercise in futility.
