    Put one of these one fits all on the F350 / 460 a few months back and over all its been a much better carb than the stock reman Holley motorcraft POS that was on it before. Yesterday I gave into the urge to nail it on a open stretch of road near the house and then it stuck wot. Its not the linkage but something internal is holding the secondaries open 3/4 and it will not release. ended up starting the truck in N and mashing the brake the last 1/2 mile into the driveway. any ideas?

    i think we discussed this carb before somehow . maybe you asked about the holley but then decided to go with the counter guys edelbrock suggestion ? can't remember if it was a manual or electric choke . your edelbrock carb part # - 1405/1406 = 600 , 1407/1411 = 750 ?
    anyway , if there is nothing that fell down inside throttle bores for some reason and linkage etc is ok then i would also check the passenger side choke and linkage stops ? i've had that kinda jam up on me before when something gets outa whack . usually if you just work the left n right linkage a little back n forth it'll kick free . memory .
    that's my guess . workin now , will check later when home .

    Took it off this morning and the bottom flaps are stuck fast 1/3 open. Cannot see anything in the linkages sticking or out of alignment. Weird. Its still under warranty so I'll just exchange it.Scary part of this is my daughter comes over and borrows that truck once a week to haul her trash to the dump. glad it didnt happen when she was behind the wheel.

    actually had a guy stop by this afternoon , had a #1406 that he wants me to do for him . I had it apart and was playing with the linkage . I think I noticed it before when the choke was full open or full closed maybe ? some kinda linkage interference maybe ? at least on mine .

    Messed with it long enough on the bench for it to finally snap shut. Tried to duplicate the malfunction again but it wouldnt do it. Exchanging it in the morning for another.

    FYI - had the 1406 back together yesterday , they picked it up . before they did I was playing with the linkage . I could get it to stick open at about 1/3 throttle - it was the swing arm linkage on rear lower left side of carb . if you manually played with choke linkage and it pulls that up just right it does not let throttle return without a little nudge . I could see where it may allow the same to happen at full throttle if somehow it could force its way over other linkage piece .

    Either something on the secondary shaft is binding, or the throttle plates are warped/bent. I had a notch in the secondary linkage holding my secondaries open when I took my '67 to Colorado Springs a few years back. Luckily, I just had to replace the rod with a fresh one. The tang on the secondaries is squared off, and the slot where the rod sits has sharp edges. The edges wore a notch into the rod, and it caused the tang to hang up & keep my secondaries 25% open all of the time.

    So far the new carb is working out just fine. Took it out for a ride this morning but didnt have an opportunity to hammer it.

    BRIZ! What is shakin.
    Ya know, I think your just gonna have to Hammer that thing. Because you just wont know until you do.
    I hope that was extremely enlightening.

    I had my Riv stick open ounce while test driving it before I bought it from my friend. I had my hand on the shifter and the DA-WOOP made me accidently drop it in first as it got stuck. Turned off the key and rode the brake for half a block before it would stop running. Seems like it would have kept running even with the key off. It had the original points dist.

    Once made the mistake of attempting to replace the injectors in my F250/ 7.3 diesel. Found out after the fact that theres several steps to be taken prior to removing the injectors. One of those is draining the fuel rails. If not all that fuel goes into the inter cooler. Took the truck for a test drive and stomped on it giving it enough vacuum to draw that fuel into the engine through the turbo. She took off and would not stop until the fuel was gone. Once a diesel is running the only way to shut it down is to cut the fuel. I was key off, white knuckle on the steering wheel with both feet pushing the brake peddle to the floor and it was still pulling on me. Next time it went to the shop for that work.
