I have a Holley 4 barrel on the 383 (super commando)RR and i have had this intermittent fuel leak which i thought was coming from the brass fitting on the carb that the hard line threads into. So i gave it a slight tightening and it moved quite easily. No more fuel all over the manifold. Well today is a different story,there are soft plugs or whatever we want to call them, and they have this semi hard compound over them and the one right next to the fuel line inlet leaked out some fuel today and the compound used to seal that plug crumbled away.
NOW WHAT? Don't say new carb unless you mean it!!
Thanks!
 
What is this hardened substance that is on my carb locations,perhaps soft plug areas and can it be resealed where it came off?
 
That turned out great. My original is still sitting in a box, under the workbench... it was almost buried in a shallow grave out back. I need to buy a rebuild kit for it.

For $250 I would send it to this guy, its better than new and set to go. The flaps on the bottom wouldn’t move on this , it looked like it had been outside for years, everything is brand new again. If you bought all new stuff plus the kit and your labor and chemicals you would be close to the $ 250 mark. Thanks
 
Who’s..This guy? Still anyone know what the goop is that is on the soft plugs? Was it put on to think someone was stopping some leaks?
 
Alright here’s a pic of the carb with some of the compound in other spots. The leaker is right by the fuel line inlet.

Looks like somebody has removed or at least monkeyed with (can't tell exactly by the photos) the factory metal plugs and tried to reseal them with some kind of goop. You might be able to reseal the leaker with some JB Weld or similar epoxy. Better fix would be to get new fuel bowls...since somebody has obviously already tried to seal them up before...
 
That's what i thought on the messing with the plugs. I did however only had some Permatex hi-temp silicone and put it on the plug that was leaking, kinda think that their won't be much bond because of trace contamination from fuel.
I'll check in the morning,not holding out alot of hope. Maybe the next cheap step will be the JB weld.
 
Call Holley and they can sell you any thing you need for the carb. Yes look's like in steed of getting new bowl gaskets they use silicone. Not a good move. New plug's and O ring's also.
 
Thanks so much for the info! I got some JB weld compound (putty) it says it is fuel resistant so it’s my temp fix.
