I've been a chump these past couple months trying to figure out this off idle stumble, but after watching this video I went out and checked the lever and it had so much play you could almost put a pencil in it. Immediately closed the hood and took a walk to ponder my existence. When I finally came back, I adjusted the lever and the ole 460 runs like a champ now. Thanks Luke.

Your video was MUCH better than any Holley tech vids explaining how the pump is supposed to work, I “all of a sudden “ have a hesitation when I stab the throttle, even on the highway, if I backed off the throttle then back onto it, a split second hesitation, NEVER would I have considered the fact I lowered my idle and that directly affects the pump operation.

I just finished a nightmare build that went from a Ford 400 to a 351M to an actual 302HO crank in a 351M block, by the casting codes, with 400 heads. Don't ask it's a long story. and on top of that, new cam, intake, card, valve springs, lifters, etc.and with all the changes getting the timing right was a battle and so I was thinking timing and hadn't even checked closely the accelerator pump. Sure enough it was loose as hell. tightened it up and what a difference... Thank you!

Then I started over and checked the timing. I had it on manifold vacuum, so much for double checking, and was running 21 degrees at idle. LOL. I put it back to ported. I am back to 12 degrees mechanical at idle and 28 degrees maximum mechanical, with around 38 or 40 on vacuum. I reset the carb and it runs awesome. I wondered why it wasn't starting so easy.

Great video Luke as always. It’s funny how the way different people absorb and interpret information, well differently, and I think that’s one reason I gravitated towards your vids, in that you generally deliver what I consider to be vital with instruction videos, and that is concept. The concept here is the dynamic relationship between off idle adjustment and the accelerator pump are joined at the hip with seemingly everything like AFR, initial mechanical advance, jet sizes, the throttle linkage, etc. it’s quite a bit but slowly I’m beginning to understand how necessary it is to comprehend the myriad of relationships between components, their adjustments, and not a single complements adjustment can stand alone. That would make one hell of a video, a video that explains the woven interconnected dynamic mess of displacement, bore, stroke, fuel delivery, variables in fuel delivery, eliminating variables in fuel delivery, timing, compression, valve events, engine under load, low load, heavy load, elevation, temperature, gearing, vehicle use, and the endless compromises one must understand in order to tune all of it to meet a very specific goal, which for everyone is different. Oh boy, there’s no end to the learning. Thanks for your sharing

Good explanation. My Holley book for a street dominator I had years ago said I should have a little gap (I think .015") between the accelerator pump arm and the throttle linkage. From what I've read, you may want a split second of air before spraying fuel into the boosters. I feel like this will vary between engine combo's so maybe no gap or maybe a little gap.

The pump lever would stick every time after adjustments over and over. It made the throttle too stiff, but I rigged a return spring for just the accelerator pump lever to stop that stumble. It ssems a bad design. No matter what pump or lever or adjustment, the thing will only return halfway, so next time you gst no fuel until it takes up the slack. Nobody talks about this but I saw it on every Hoĺley.

I have had some stumbling problems before and did all the same ol fixes, plugs, wires, carburators, edelbrock, holley, demon, timing adjustments, fuel filters, fuel pumps, coils, distributor cap, roter, etc, still the same dead dog stumble from dead stop..... What could it be??? It's kinda rare and something you may never see or even guess that could shut down a high hp engine. Are you ready? AIR CLEANER....It has happened to me twice, a small air cleaner caused me to buy two new carburators, Holley 750, elderbrock 750. Finally exhausted one day and out of patience and money I inadvertantly closed the hood for another test drive. I had forgotten to put the air cleaner on as I was in a hurry and not just a little aggrivated. A 460 ford engine setting in a 1985 mustang should scream, and in this test drive it did. I couldn't believe such a simple thing a a undersized air cleaner could shut a engine down like that. One of the reasons I brought this up is I just built a 1971 plymouth Duster with a big block 400 with 10.5 to 1 pistons, 750 edelbrock and all the goodies. Changed the gear to 373 and ready for that test drive, flat on it's face, barley squeaked the 9'' wide tires. Oh what a disappointment. Had to be the carb, no the timing, what could it be? Then I remembered a long time aga a 460 ford engine. I ripped the small breather off and lined up on the road for what I belived would likely be another failure as this could never happen twice in a lifetime. It burnt the tires so bad that it climbed into third gear still smoking them dudes. Crazy right, Strange but true. Thanks for listening...

@raygee11382 жыл бұрын
If you read the adjustment portion of the instructions that come with the rebuild kit you'll find the proper procedure for setting the accelerator pump arm preload. In a nutshell you work the throttle arm so it's at W.O.T. with the pump arm fully depressed, then you use a flat feeler gauge to set the distance between the arm and the pump hex bolt by turning the lock nut. It's as easy as that with no guess work involved.
@ThunderHead2892 жыл бұрын
No, with it fully depressed there will be no clearance - that’s just a test to verify you aren’t bottoming out the pump arm which with the stock pump cam is pretty impossible to do. You make the clearance adjustment to your pump lever which should be zero lash with no load with the throttle closed. Thunderhead289
@KC9UDX4 жыл бұрын
Your explanation is close, but it's simpler than that. Liquid fuel has more inertia than air. So it takes longer for fuel changes to happen than air changes. The accelerator pump preempts the lag in fuel delivery.
@ThunderHead2894 жыл бұрын
It takes longer to draw the fuel than the air, so mechanically it is applied to bridge the gap. I’m not sure what I said that wasn’t correct, but I like the technicality of your explanation

It helped, but still occasionally stalled. We moved from Illinois to south Florida and a friend with more mechanical knowledge adjusted the carb and I never had the issue again.

TH289, I have a stock 83 mustang Gt, the 4180c bowls are leaking and just WONT seal, so I bought a 4160. Long thing short Leaking down into cylinders. Okay I got screwed whatever. Switched to another 4160, this one worked amazing on a 454, it runs great, won’t start back and grunts like it’s high in time, but it runs smooth and good. Would it be a adjustment or a Fuel pressure issue? As it’s the second 4160 having similar issues. But not flooding cylinders(hydro lock). But the stock 4180c fires up every hit of key no grunts or anything. No gas nothing, just key and it starts. The 4180c was stock 7-9lbs of fuel pressure, the 4160 is a max of 7 lbs, should I Check and Lower fuel pressure or any ideas? I’ve been pulling hairs

I am aware of these adjustments however I'm having a problem with any carburetor I put on my firebird 421ci If I slightly open the throttle, it stumbles. I have tried setting the idle circuits lean and rich. It still happens. Intake leak maybe?

Sounds like it's more ignition timing related than anything. When testing with vacuum advance disconnected, id expect at least 12-18 initial, and 30-36 total, all in by 3500 at the latest

I put a reman 600 Cfm holly 4 b on my old GMC snow truck at the end of summer, I didn't have time to play with it, I got it started, but at low idle, it ran ok after it got warm, I put fresh gas in no methonal, , And now its -7 outside, a blizzard, and it wont start, I have to pump the hell out of it to get it to even try to start, but it wont, I did have it started 3 days before and adjusted the curb idle down a bit, , So how do I get it to start in real cold weather?

Wouldn't the number 2 hole be best on the primary side for a foot brake racer that has to come up on the converter to 2000 rpm so your not already using like 20% of the pump cam?

My throttle linkage is functioning correctly, but I still have an off idle stumble. Even when I just try to bring up the idle slowly, around 1500 rpm the truck stumbles and BF. But if i pump it past 1500, the truck sounds good and I know the timing is good. Any ideas anyone?
