  • The new season is upon us, and as cars are brought out of winter hibernation, there are thousands of guys all around the world that are going to have to deal with problems that didn't exist when they put their rides up for storage.
    Holley carbs are notorious for developing random fuel leaks after they have been sitting for any amount of time. Here are all the common failure points and how the simple fixes that will get you back on the road with a minimum of cash and hassle.

      Don't ever use those silly bypass caps in the help section of the parts store to cap a hose fitting.
      Use a bolt ,piece of hose and a clamp.
      Sure they look better ,but give em 6mo and they crumble in your hand.
      Damn things piss me off as a gen tech because psi engines come with em from the factory.
      Replace em at startup ,or in 6mo when it blows and sprays coolant all over.

    If you have a Holley carb on anything, a car,truck,boat,etc.. it's always a really good idea to look at the carb from time to time and constantly check for leaks and check for any deteriorating o rings, accelerator pumps or fuel line, it's best to catch the leak before it happens so you don't burn your ride down, holleys always seem to have a bad habbit of springing massive leaks at the worst possible times. That's why for most daily driver, low performance vehicles, I always opt for a rochester or afb style carb Soo much more reliable and less likely to start leaking. I have seen quadrajets that were over 40+ years old that have never been apart that have zero leaks, can't say the same for a Holley they always leak.

    Back in 1975 I had a Holley 600 on a 65 Mustang. it was not unusual to be driving along and suddenly smell gasoline, pull over, open the hood to find the crossover pipe O rings leaking. But I always had a box of Holley gaskets and parts in the trunk so remove the float bowl and replace the O rings and continue on. Oh, the joys of owning a Holley. 😊

    Back in the day, I was a member of our local volunteer fire department, which was equipped with hand-me-down Ford C-cab fire trucks with gas V-8s. The Holley carbs on those engines gave us fits, since the trucks sat so much. Even worse, our old firehouse was so small that we could not raise the cabs to access the engine inside the house. Don't miss those days! Rochester Quadrajets get a lot of grief, but I would store boats with them on 305 and 350 GM engines for 6 months at a time, and they would fire up and run fine. Thanks for the video, Uncle Tony!

    I learned that Teflon tape lesson the hard way. As a young lad, I Teflon taped the shit out of some fuel lines, and some of the tape worked its way into the carburetor, and got stuck in the needle and seat. Had to nurse the car back home and was driving myself crazy figuring out the problem, but then I showed it to my father, who, of course could tell what was going on right away.

  • @ohm1945

    Always had Holleys, most of which are as Tony said, the 600cfm vac secondary square bore (4160 if I recall correctly). Only months ago, got hold of a used 625cfm Street Demon. Sure, more fine tuning with metering rods, vacuum springs and the like , but no leaks due it’s bowl design. Better for a cruiser or mild street car I’m told but I think the large secondary barrel is ideal for WOT launches.
    Barry Grant got it right on that front.

    I've been messing with Holley carbs for 40 plus years too! I used to have boxes of them under the bench. People would get fed up with them and just give them to me! Personally I love Holley carbs. Anyway you're spot on. The first start up of the year I always leave the hood up for awhile and check to see if there are any leaks. If there are leaks I fix them and that is usually the end of the problems for a couple of years. Great video.

    One thing you missed talking about is that some Holley carbs use a rubber bushing of a sort on the transfer tube as opposed to o-rings and that when putting on the transfer tube to spray the oring with silicone spray so it slides in and does not roll

    Had Holley four barrels on a couple of old medium duty trucks until the early 2,000s. Those trucks sat more than they ran, all winter, six months up here. Even after Minnesota went to ethanol in the 90s I really didn't have trouble with them leaking. Sure occasionally I'd replace an O ring but it wasn't like an every spring ritual. I'd say it's definitely the O rings today, no idea if there's still US Made ones available today. You can bet the ones at Autozone or whatever aren't made in the States.

  • @roflman

    The leaky transfer tube got me for a while, because by the time you shut the car off and lean over to have a look, the fuel has dribbled down around the pump diaphram and you think you've got a bad pump shot. (btw the teflon tape does work well temporarily on the transfer tubes if you don't have an oring handy, seals well for a few weeks before the gas melts it)

    • @sewing1243
      @sewing1243 Před rokem +3

      If anyone is tempted to use a teflon tape then at least buy the fuel rated version: yellow PTFE tape
      The plain white teflon PTFE tape is best used for water and it does not have resistance to chemical compounds (like gasoline). The yellow PTFE tape will work for household plumbing (but a roll of the yellow costs twice as much as the white tape).

The rubber on it can deteriorate too if it gets dry too many times! Great video as always.

    I honestly do mean this, every time I watch this channel, it makes me consider more and more going with carburetors on my Honda. I know people are going to laugh at that, but a 1989 Honda CR-X that was B18 swapped (1.8 Liter DOHC 4 cylinder) running a ported VTEC head, 13.5:1 compression, TODA VTEC killer cams (insanely aggressive cams), and SS Works' own carburetors made 230 horsepower and set a lap record in the early 2000s around Tsukuba Racing Circuit of 59.1 seconds. Honda engines love individual throttle body setups and individual carb setups.....and if I really wanted to go for an all out build, carbs would ironically be easier to deal with than individual throttle body tuning.

Granted my GTO only gets driven 500 or so miles a year but it sits most the winter without running. Always found it very reliable and prefer Holleys to the Qjet for ease of starting. I don't even use the choke and it fires up easily. I also have a 750 vac secondary which has been sitting for years. I bet that would leak like a sieve though, so I need to rebuild it for a back up.

I had more than one come fresh out of the box with that transfer tube leaking. I think if I were doing it today and wanted to buy new I'd get the Edelbrock 600, or maybe the Brawler 600 with the mechanical secondaries, it has no transfer tube.

    Even "the good old rubber" goes bad with modern gas. The alcohol (and the additives that keep it with gas for few months) make the rubber swell and harden. When there is no gas they shrink back, but as they are now hard, they do not seal any more. I talked to a guy that has sold carb rebuild kits for 30 years, and he told that with the old leaded gas carbs lasted easily 30-40 years without problems, now about 3-5. Happy guy, as his business got boost...

Saw 3/8 Fi line burst after melting from some new additives to pump gas and had 2cycle gas lines leak when using regular 2cycle oil with 10 % ethanol gas. They keep messing with blending of fuels without any warning . How many engines got ruined when the took the fines out of Motor Oils without warning ?

    Holley Golly, I double the o rings on the transfer tube. I drain and store carbs 😩 in climate control and wonder if I spray PB or WD through them helps?

    The accelerator pump cap will also get distorted with time and will leak. Not a flood leak but will create a yellow varnish on stuff under it associated with this slow leak. They can be sanded flat and reinstalled.

    We had a beautiful 406 Ford catch fire in the pits with three Holleys. I hate them to this day. That was over 50 years ago.

    The flange that holds the o rings in place is far enough back on the transfer tube to actualy put 2 o rings on each end. Just a little insurance, I've been stacking mine for many years and never had 1 leak.

    Hey tony, so I have that same 600 carb with the transfer tube on an 81 318. And im having this weird problem where it'll start and idle perfectly but after 5 mins it completely dies and wont restart until a full day passes. And it doesn't have the factory brain box ignition, it has a pertronix distributor on it. Thanks

      Are you loosing power to the coil or the distributor when it dies. Determine are you loosing spark or fuel?

    If I have a carb, I run ethanol free. Big engine or small engine. My problems vanished.
    Thx for the vid, UTG!.

    Will a leaking needle and seat cause fuel to get into the crankcase? Already changed the mechanical fuel pump.

    @kenwatts5410 Před 10 měsíci

    BLP Carbs in Florida sell o rings for the needle and seat made of Buna material for 35 cents, I use Allstate Carburator and buy everything else in bulk, at the end of the cruising season maybe drain the carb take it apart and vasoline the critical o rings and parts, just a thought.

    My old TS 125 does that.
    Leave it sitting 6mo with an empty tank ,and fill it up and the fuel valve pours fuel out.
    So leave and come back 20mins later and it's stopped.
    Can't recall how many times I've seen it do that over the years.
    Let the fuel swell up the seal in there and it stops.

    Unrelated question; what CFM carb would you pick for a 302ci engine that is not going to rev over 5000 rpm. The math tells me a 500, but is a 600, or 650 too much? Which would function the best? Thanks

    My street avenger is leaking from the glass sights. Would this indicate stuck needle valves or are there o-rings at the sights?

  • @jackinthebox6143
    @jackinthebox6143 Před 9 měsíci

    Also the accelerator pump diaphragm (?). They go rock hard in no time. Theyve brought in a new one made of something greeny bluish that's supposed to last. Online they were charging $50 each!! I think vaseline helps these things last but I may be wrong. It just seems to stop them drying out.

    Thermoquads have X ring o-rings at the bottom of the primary wells. Yes alcohol(ethanol 10%}dries out the non nitrile o-rings.

    My gf has a ‘65 slant six with factory Holley and I heard these are prone to leak too. Is that only the float bowl gasket or o-rings somewhere too?
    I hate Holley and love Carter but try to find an affordable non worn out Carter BBS for a slant six in Europe… 😂

    Most carbs I've rebuilt ran better afterward, and none of them ran any worse.
