I'm here where I'm safe. I'm following your progress.
Get them dual quads opened up and suck some of the unhealthy air.
Get them dual quads opened up and suck some of the unhealthy air.
Give me a few minutes sure I've got to eat dinner real quick..At what speed? IF your at 1800 rpms in 1st or 2nd it should take off. If you are at 1800 rpm's in 4th gear and mash it, you are making it more difficult but I still believe it shouldn't cough and do a major "cut-out", but it may be hesitant.
I'll be interested to get it to the track because when it's on like I said it's ON!!
my buddy just sent me a video of me taking off from his house that was only about 10 seconds long but it only took two for me to disappear!!..
plenty of threads about all that I like to talk about the car to get away from all those worries or concerns...I'm here where I'm safe. I'm following your progress.

have all day tomorrow so what it really boils down to is three more trips around the neighborhood. Springs in now and tomorrow plan on trying the green witch came with the carburetors. Then on to the pinks. And then one more try with the silver... Remember I went back down to those directional .031 Holley squirters.. I have the street demon 42's and 47's as well.So...I think you should go out and get some vacuum reading at a cruise. Then, set your springs to open a few numbers below what cruise vacuum is. For example, if you cruise vacuum is 15 inches, set your springs to open at say...11 inches and see what happens.
If your idle vacuum is say...only 9 inches, you can test to see if the metering rods being up at idle makes a difference (I don't think it will because the idle feed system is very similar to a Holley and the Holley guys have been getting it wrong for decades) or if it doesn't matter. I don't think it will matter.
You can tell by verifying your A/F ratio at idle with say...a spring that pulls the metering rods up a 6 inches of vacuum and compare that to the A/F ratio at idle with the 11 inch springs in it.
If I'm correct, the A/F ratio will be the same at idle with either spring in it it, and the higher spring number (pulling the metering rods out of the jets sooner) will help clean up the lean spot on cruise tip in.
Physically the higher the gear the higher the hesitant... I'm also under the timing curve at 1800 RPMs as well...At what speed? IF your at 1800 rpms in 1st or 2nd it should take off. If you are at 1800 rpm's in 4th gear and mash it, you are making it more difficult but I still believe it shouldn't cough and do a major "cut-out", but it may be hesitant.
it's like a highway gear and tight converter, exposes every imperfection of the carb (in your case carbs). If you roll along at 3000 rpms in first and mash it and it seems ok, that's just masking the issue. 3500 stall converters and 4.11 gears do the same for an automatic. If you stay with it, you'll tune the hesitation out, even at a low rpm. That's when you know it's set up right. Even though it's different, my car was kind of the same with the factory converter, 2.45 gears, and getting the 750 Double pumper to work from a dead idle mash. I got it with zero hesitation from a low idle mash, and you will too. Now, with 2.94's, consistent 1.8's. Don't hide it with rpm's and the clutch. Stay at it till it works. Sorry I don't have any suggestions for you as you are trying one thing after another.Physically the higher the gear the higher the hesitant... I'm also under the timing curve at 1800 RPMs as well...
I see what you're saying I just looked at it. I noticed the slot there before but wouldn't think that it would have any effect. What I'm wondering now is if I don't just straighten that Rod out to be at the back of that slotted opening from the beginning??..Hi, did not read the entire thread….but had to deal with one of these carbs before. I noticed the arm for the accellerator pump is in a slot of the throttle Lever, no 1:1 movement when you get on the gas. That caused a stumble everytime…..i put a screw into the Slot to take up the space….now direct movement of the acc.pump arm when the throttle Lever is moving…..no more stumble or lean spot. Check it out!

Again the stumble not off the line more so from a cruise to open throttle?try the screw trough the Slot to "fix" it....so you don´t have to bend arms back to original if it does not work ;-)
Michael
yes it's something that I've been watching very closely. It does seem to move with the leaver and pump immediately...ah ok, understand. But as far as i remember the throttle Lever had to move quite a bit before the acc.pump was activated in my case. So could still be that the acc. pump is your Problem.

Well I drilled them and put them on. It wasn't an easy process to take the old ones off and put the new ones on. That Rod that they're screwed to spring loaded.. the nice part is when I took it off I slowly let it rotate backwards and it was two full turns exactly. if I wasn't mistaken the front one was closer to three full turns so I was able to even them out when I put them back. Really there was no telling except for adjusting off of the stock setting... of course I took it for a test drive but it's mid-to-late afternoon and there's lots of traffic and I'm not looking for a ticket or anyting. The true test of this one will be a ride in the country or on the freeway. Again all the primary circuit settings were running pretty damn good...
Of course the ultimate ultimate test would be to take it to the track. If I see familiar numbers or better... There will be an Edelbrock and Carter performance for sale...
I was siphoning out the snowmobiles of their non-ethanol super today and I already have a five gallon can of 110 Sunoco... I may have to take the back roads and do more testing....That's progress. I think you can write off the track for awhile.
I took close to a 50 mile drive out in the country little highway mostly crew speed... Of course without question a few wide open throttle shots like in 3rd gear and a little bit of City...
The wideband was showing hi 12's and low 13s at Cruise... It was looking like 11.5 or so at wide open throttle..
still some small flat spots at mid throttle but really this was just to kind of enjoy the car for a little while and get out of the house... I filled it up before I left and filled it up when I got back and used about four gallons for the 48 or so miles..
I checked the passenger side plugs again and they all look pretty much like this one...
