I really don't see the issue w/ this. The problem isn't really Holley's fault if it is zinc pest and I didn't post this bashing them. Simply asked if anyone else had seen this before.
Not to mention they have always treated me right and sure made a good offer to correct this issue.

I thought Andy was joking on the Zink Pest. Did the google search and it looks like that is what infected the metering block .

I just had a buddy at work with the same issue this summer. Not sure how old the carb was, but it wasn't even close to new. (5-10 years?) They told him it was part of a bad run/era of carbs. He sent it back and they gave him a brand new carb of his choice.

Call them...they have a good history of taking care of customers.

They are sending me a brand new carb. Sent it out yesterday.

good news !

Good news and great service.

Can't argue with that!!

Not entirely true.


All gasoline brands have both pure and ethanol-containing gasoline under the same brand names. For example, Shell V-Power ranges from 91 to 93 octane both with and without added ethanol. It just varies from station to station, and it's up to the station owner whether or not to sell pure gas. Gasoline refineries walk a fine line with ethanol blends due to automotive manufacturers fuel systems ethanol tolerance levels.
Other methods of raising octane levels in gasoline is the use of MTBE and ETBE. These compounds do not cause deterioration of sealing components used in automobile fuel systems.

Kudos to Holley. It's good to see that there are still companies that stand behind their product.

MTBE is not used much, if at all, any more because it dissolves in water and contaminates groundwater. Then you drink it.
Gasoline companies by and large switched to ethanol.
Ethanol isn't such a problem if you drink it. I prefer ethanol made in Scotland or Kentucky to be mixed with the water I drink.

That carb looked really old to me. If Holley is making good on it, that is impressive.

I saw the pictures and it resembles alkali-aggregate reaction which affects concrete.

We literally use hundreds of Holley carbs ever year. We had this same problem on several carbs a few years ago. There was a known bad batch of plating that we returned many that had specific manufactured dates. Holley made good on all of the carbs we had issues with. Glad to hear they took care of you also.

The carb in the pictures was bought brand new in 2007 I believe. It was the complete 6 pack induction kit from Mopar Performance. Came w/ all 3 carbs, Edelbrock intake, air cleaner, linkage, fuel line, etc.

BTW...as expected, this carb was one of those in the bad batch of castings they had about 10 years ago. Said they were giving everyone who had an issue w/ this new carbs.
Both of the guys I've talked w/ up there were great to deal with.

That's great customer service right there........
