I just wanted to get this out there. I was as surprised as everyone who has now seen the pics. It just goes to show you, send in your product registration cards. That way situations like this can be avoided since they probably would have contacted the people who purchased the inferior units. Holley never stated to me that the issue was strictly related to the metering block and the recall also calls out the fuel bowl. I think it was either a bad batch of material or a flaw in the final coating process. Regardless, I would check my Holley carb even if it was made after the recall dates. I know the older ones are fine. I have several.

That's what the majority are made from. They also have aluminum versions now.

This is completely inexcusable.... What has happened to quality? BG carbs are or were junk with the shavings in the bowels, Do these people even understand the basics of machining parts? eventhough good carbs I have lost faith in Holly now. I have heard a few other stories but figured there was a reasonable explaination. I was getting a 650 for my 390 ford, but I can tell I am going to buy a rebuilt carb for a reputable builder... I just don't get it... I can see there being occassional defects but this is completely out of order...

Is the aftermarket now so desperate for profit that alot of crap is being produced out there? I am not saying all, but its alot

Sorry for the rant, but what has happened to good old made in the USA quality... Even things that they say are made is the USA is produced in China....

Blessings,

Sounds like another reason to visit Patrick James @ www.pro-system.com

I just wanted to add that the carburetor I found this problem with was a model 3310-10. It was a 750 SP vacuum secondary unit with the aluminum finish. I'm not sure what other models are affected since the recall does not specify a particular model # or surface finish.

My guess would be that they tried to save money by getting the castings done in China.

Charley...

Now be nice! We must be PC and share our wealth with all the world!

You think maybe the guy that was boiling down cardboard and serving it as dough balls filled with pork -- is now in the casting biz??

I spoke with Holley today and had a pretty in-depth conversation with their tech guys. They told me that though the problems appear to be in carburetors manufactured durring the end of 2005 and beginning of 2006, they have found that some made durring that timeframe have not shown any corrosion at all and some have had more corrosion than the one I posted pictures of. They told me I should recommend too my customers that they look at their carb and inspect them at the first sign of a problem. If it is corroded, they will replace it for free. I also asked about possible fuel additives causing the problem since ethanol is in almost all fuels now. They stated that they investigated that possibility and found it was not a factor. Their testing concluded that there was a "casting problem" that has been corrected.

My guess is they changed their process, supplier, or both to cut costs and it backfired. It's just a thought
