Ok, so I got some cup tip set screws a while back and drilled them for .031s' I put them in and drove around and still getting a slight stumble at cruise 2500 ish. I disconnected the secondary linkage to see what would happen cruised around and the stumble seems very slightly less. while I had...

I just drilled the old ones out slowly to the depth that they were and them tapped them ... After doing some research on the old interweb.. I pretty much figured out/ or at least see that everyone else that has done this use the set screw type.

Hope this uploads

Help, and question?! So, I got my idle feed restrictors in. But I think I may not have the kind that I need. I got the quick fuel brand which is a 6/32 but has a head with a flat screw driver slot. I got my old idle feeds drilled out and tapped for the 6/32 but when I screwed the new ones in I...

I was checking my spec sheet on the carb where it states all of the bleeds. It shows an interm air bleed but then states N/A. just curious about that... I ordered some .030, .031, 0.032, bleeds and some .071 and .073 bleeds. I also did a bit of tinkering, I put a vacuum gauge on and at idle and...

This may be a stupid question, but... Should My timed park port should be plugged and not left open since my MSD distributer doesn't have a vacuum advance???? also, I'm going to be ordering some idle feed restrictions. Should I also order some idle air bleeds as well, and what size? Thanks.

I have the initial timing set at 17-18* with an 18* bushing in so it's 36 all in.. Sorry, what is the IFR? is that the idle feed restriction? and where is that at? sorry "novice" I have been trying to educate myself as much as I can.... Which springs did you say? 1 of the medium "blue" and 1 of...

So I'm a bit of a novice when it comes to carb tuning. And I am trying to get this tuned in. It's a newer AED 750 Ho carb. I have a wideband kit on it which is helping a lot. I am trying to get my cruising rpm air/fuel ratio a bit leaner as it is running at about 11.5 to 12.5 and in between...

yeaap. the 20-7 bracket as installed, but it looks like it would just move the linkage out away from the carb, but not up away from butterfly centerline for more leverage or travel? and yes it hits both the black throttle linkage bracket and also silver return spring bracket. Anyone any...

Well Awesome. got the 20-7 holley throttle bracket in finally and went to install it and found that it won't clear the throttle cable bracket and return spring setup that is currently on it. even better I'm pretty sure I had a throttle bracket that would have worked but traded it with some other...

I was hoping it was that I just needed a some sort of bracket extension. I'm ordering the holley 20-7 bracket extension. Hope that gets it... THANKS ALL.

That is what I was thinking is that there needs to be more travel at the cable because it seems the pedal hits the floor before the carb is open all the way. And at the carb end it seems there could be enough cable pull, but its just that the pedal is at the floor already... What would be the...

Hey thanks. No, its not a vaccum secondarie. I thought also that maybe it was getting some interferance but nope. While she had her foot to the floor I pulled the throttle back the rest of the way and it opened fine. Also if she, mashed her foot into to the floor it would open slightly more but...

So this is how little the secondaries open.

So I was messing with putting on a new filter on the car today. and just wanted to check this since one of my buddies had the same problem on his car. I had my girlfriend push the throttle down to the floor normal without mashing it in while I looked down the carb. And low and behold it only...
