Holley Street Avenger Corrosion!!

[protour73]

I read a while back about Holley Street Avenger carbs that had a corrosion problem, so with the thought in mind of doing some carb cleaning, I got a rebuild kit and tore the carb apart and found this. Has anyone seen this before? Is this the problem that Holley advised about? Or is this something else like the type of gas (with ethanol??) put into the car?

Also noted two different floats, brass in primary bowl and the modern material in the secondary bowl.

Well this was a fun little adventure.....sent the carb off to Holley and they got it on Wednesday. Took untill that afternoon before they got a look at it, and the tech called me back. The carb will NOT be covered under warranty, as the damage was due to "water contamination" or "corrosion from alcohol" They asked if I ever ran E85 in it, NO..... I explained that there is fuel in the bowls in a temperature controlled garage over the winter months. They said, I need to drain the bowls when sitting for long periods, or use a Sta-Bil type product. I asked where in the owners manual does it instruct that.......it doesn't.

My point to them was that it is Holley's responsibility to tell the purchaser how to properly maintain the product. So basically I was screwed.....I explained to Shawn the Tech, that this was a horrible non-solution and I was extremely upset.

Thursday morning my cell rang, It was Shawn from Holley Tech Support. He talked to his manager and they agreed this was not a good ending to this issue and he offered to send me a brand carb for $75, which was their warranty repair charge (normally for the age of my carb $100 is the cost).

I explained that it was against my principles to have to pay anything, but $75 as opposed to $400 for a new one, was the lesser of two evils. New carb arrived today and will go on the car tomorrow.

I don't think this is an issue with the Dichromate finish on Holley's. I think the Street Avengers are a zinc finish....which apparently is vulnerable to corrosion from the Ethanol in the fuel. Lesson learned on this one and buyers beware if you are thinking of purchasing a Street Avenger from Holley. Drain the carb if sitting for long periods, or use a Sta-Bil type product. Previous to this I did not, I know many folks that don't and never had a problem.

Good to hear you got it resolved. Makes me want to run down and take my 670 Street Avenger off my FFR and check it out though . Then again... sorta makes that FAST EZEfi that much more appealing.
