I used the search first, didn't find anything. went to change the screw-in fuel filter/clean up the inlet fitting on a holley 1946 and the inlet threads came out with it. i'd ordinarily just tap it a size larger and throw a different fitting on there, but this carb uses a needle and seat in its inlet fitting that has to be there to keep gas off the manifold. this car's been down for a while, and i'm getting pretty sick of not driving it, so i'm awfully damned tempted to just epoxy the fucker back in place. seen jb weld fall apart before, so i'm a little afeared of that. recommendations, fellas?
napa sells a kit to put epoxy threads back in a stripped carb works ok if u put the fitting in and leave it
all i could find at mine was oversize self-cutting repair fittings for four barrel carbs, which won't (obviously) work with the little holley--you mean there's an actual epoxy kit of this? any more info on that?
POR 15 POR Patch, Nothing to mix, just apply it and let it sit for 24 hours or longer. Best shit I have ever used.
Yep...JB Weld held up the fuel fitting on my Chevy II carburetor for over a year of daily driving, till I finally changed the engine.. just clean everything well, a little on the fitting threads, a little on th carb. threads....you should be fine. Mike
You might have to make sure the product you use won't be eaten up by some of the new gasoline mixes. I know fiberglass tanks and stuff like that will be destroyed, but not sure if epoxy has that same issue. Don
JB'd a float bowl together on old shovelhead just to get it running.2 years later never leaked a drop.
thanks boys. moneymaker-is there a store you know of that stocks the por stuff, or is that a strictly online type product? the jb weld consensus is what i expected. it is pretty good stuff, though, and oh so available. i worry about the constant exposure to fuel, but maybe i'll have to go that way anyhow. anybody else? i know i'm not the only one this has happened to. don't the holley 94s a bunch of you are running have an inlet needle and seat? what's the fix on those?
Marine Tex epoxy. Its supposed to be more fuel resistant than JB Weld. Quadrajet rebuilders use it to seal the leaky plugs in the castings. Dave
I used it to hold the petcock in the flat bottom tank on my pan until I finally rebuilt the entire bike and replaced the tank. That was about 4 years and gawd knows how many miles. The tank developed leaks that got patched with JB weld but the petcock never leaked a drop. I have used it to repair carbs when i was off roading in S Mexico in the '80s. I don't know how it will hold up to modern gasoline and additives but it is epoxy resin. I would use the JB weld for aluminum if I was going to do it.
Once I cut the entire tank shell off of the bottom of a motorcycle tank .welded it back after dent and holes were fixed....JB Weld over the welds and never a leak in two years use before selling the bike... I am convinced it will not deteriorate in gasoline. I do however recommend not using the "quick" version offered today -just the old standard JB...
I have had great success with white marine tex. Very resistant to gas and oil. Easy to sand and tap. Let it cure completely before messing with it.
Loctite used to make one. Permatex still makes this... http://www.permatex.com/products/au...ad_repair/Permatex_Stripped_Thread_Repair.htm though I don't know if its affected by gas or not. I too have used JB Weld myself many times and have had no issues with it.
one thing i've considered is coating the inlet fitting with some type of reasonably stiff grease before i glob on the epoxy, and letting it set up that way, so it sort of taps its own threads as it goes, and is halfway removable later (the fitting)--harebrained? as for the permatex, i'm not sure about that particular product, but what about the gas tank repair stick they make? anybody have any experience with that? the description seems to have the exact characteristics i'm looking for
I had the inlet fitting on a rochester 2bbl leaking on me once, couldnt get the new thread cutting fitting to even start, so I tossed the little filter that was in there and smeared it up with JBWeld, never had a problem with leaks for the 2 years it was my daily driver. Still holding fine when I sold the vehicle, havent heard different since.
The fitting in the bottom of my fuel tank was leaking. I melted out the solder and replaced it with JB. Constant contact with fuel for 2 years now. Still good. I've since filled a few pinholes in the tank too. Good stuff.
I used this stuff called Gasoila..i found it on an auction site..it works really good..i used it on my sending unit gasket...not sure if it would work too well in your case though...it doesnt fully harden...those jb weld ideas sound better..
i have used the gas tank repair many times with good success,but that putty needs a little space to work. i would epoxy or epoxy stick a brass fitting into carb that has the inverted flare to accept your line,then at least the line is removeable. i also vote for jb weld.
