Title: booster venturi wear?
Post by: blarson on April 28, 2012, 02:26:22 PM

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!

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.....

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

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

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
