1966 Carb help

[Gary N.]

I have an original 66' Holley and it is leaking gas around the lead seal on the fuel bowls. What is the best way to stop this? I have heard that you can use epoxy on them. What Kind? An other suggestions?

Thanks,
Gary

Re: 1966 Carb help

Gary if I remember correctly, years ago someone said you could use JB Weld to seal it. I have a Holley fuel bowl that started leaking in the same place, I did not try to seal it yet. I had an extra fuel bowl that I used. If the JB Weld does work, let me know and I will mix some up and put it on mine.
JB Weld has been recommended for use on the infamous leaking QJets, so it just might work on a Holley.

Hi Jim I repaired mine with JB weld and it worked perfect. However be sure to spray some Brake/Claean on it and let it dry to remove any residual gas from the area. Regards JR

I am sure JB weld would work fine but if your going to get the car judged the judges will pick up on it. I found a better product called Marine Tex which comes in various colors but get the gray. It gives more of a metallic appearance which the judges are looking for. Do samples of the JB weld and Marine Tex and you will see the difference. Marine Tex is available on line or at a Marine store.

Many years ago I purchased a set of plugs with an Oring seal to repair this. I had to peel the lead back to remove the existing plugs.

I have used ordinary epoxy, which dries clear. I believe that it's 3M product, which comes in a dual hard plastic syringe where the plungers are connected.
The most important step is to meticulously clean with an aggressive solvent, like lacquer thinner or acetone. These solvents leave no residue. Remove the leaking bowl, soak it so that the solvent penetrates within the cracks/openings. Agitate to be sure the insides of the leak paths are clean. Best to dry with compressed air, which gets all leak paths clean.

Fill entire lead plug area with epoxy, so as to completely cover and fill area. Let dry according to instructions.

JB weld will also work, but hard to get correct color match. The clear covering is hard to spot, unless the judge looks closely. Distract him, or steal his glasses if he starts to "sniff around".
