Holley carb 4367 replacement? - 10/14/23 03:39 PM

70 RR Holley 4367 appears to have failed... leaking from body in a couple of places.. What is a good replacement that will appear as close to stock as passible...??

Scott Harms restored it in 2012... been running fine.... but dummping fuel now....

Are you just looking for a replacement while you have yours gone through again? I literally just when through this with my 4368 a couple of weeks ago.

Mine was leaking out of the balance tube. I went to fix it on my own and made it worse. If I had more patience with and just a little more experience with the Holley I probably could have fixed it. Instead I sent it to a local place that's been around for years and has a good rep with carbs. https://www.customcarbs.com/ They completely went through it and it runs better than new. And they did a sonic cleaning on it so I didn't lose that nice Holley finish. I also gave them my spec sheet out of my manual to be sure they put it back to factory specs.

Can you tell me what that ran? Since its getting close to winter I may just send it off. How long did it take?

Is it leaking, seeping or weeping?
If leaking, drips or more, it probably needs a tear down, good cleaning and relacing the needles and seats. If it is seeping and or weeping you may be able to stop that by tightening the fuel bowl screws a little bit, not a bunch so you don't strip or break the bowl screws. Both of those conditions are caused by the fuel bowl gaskets shrinking with under hood heat and age twocents shruggy ITHS scope

They are close, so I dropped it off on a Friday and it was done on Monday. He said it usually takes 7 to 10 days though, but they were going out racing and wanted to finish up. I didn't have to pay shipping so it was $250. That said, I'd absolutely try the above advise from the previous post . If the previous rebuild was done using the reusable gaskets in particular some tightening may help.

That is a real Delima, maybe some two part epoxy that is fuel resistant, a thin coating over and around it shruggy luck I don't think it is the needle and seat, that would be easy to change but there is no real reason for that plug to leak all of a sudden when the front one isn't leaking or seeping work,
That or replace it (the bowl)work scope

Update. I took it to local carb expert who said those fixtures are famous for leaking.... he cleaned out what was there replugged with fiberglass resin. Good to go.... no leaks... runs great $20
