booster venturi wear?

(1/1)

blarson:
What would cause wear on the air inlet side of the booster venturis?  I popper my air horn off and was surprised to see what appeared to me to be a lot of wear.  A sticker on the side of the carb indicates that it was remanufactured by Holley at one time.  Do they use a pair of pliers to pull these booster venturi rings and insert substitutes or is it possible that intake backfire caused the problem?  Thanks!

blarson:
I took another look at it in the interest of trying to better describe what I'm seeing.  I think some of the wear looks like pitting.....

Cliff Ruggles:
I've seen worn boosters before, always on remanufactured carburetors.  Holley is about the worst company out there doing "remanufactured" Q-jets.  They are ALWAYS a mess!.....Cliff

Schurkey:
Not "wear", but erosion from an acid bath???

Cliff Ruggles:
Yes, probably from the "acid bath".  Holley also "tumbles" the airhorns, and the fuel nozzles are almost always bent and mangled up as well, driven in too far, etc.  I HATE so see any remanufactured units coming in here, especially those from Holley.

I suspect they farmed that work out South of the Border someplace.  I'd hate to admit that an American Company did such crappy work then put their label on it......Cliff
