Ethonal ?

[leroyd92]

I just cleaned a quadrajet that i took apart. 4 months ago. It wasn't used much after i cleaned it but the fuel filter failed and it became full of dirt...

I discovered white calcium like Stuff all over the brass parts that i cleaned a few months ago.

There was stuff caked on the float resivor and powdery white stuff all over surfaces where fuel pools up.

Is this ethonal ?

I rebuilt my 98 s&s carb last year.( first rebuild in its life ). It gets a heavy does of tcw3 every tank. There was no white stuff anywhere.

This quadrajet didn't have any added the last few months after rebuild...

I had the same issue in some Honda OPE engines. It was the E absorbing water and causing that nastiness on the aluminum parts. Switched to non-E gas and no issues since. Local repair shop said it was real common.

Everyone talks about ethonal being bad and ruining fuel systems. I have never had such a thing happen that i could point to ethonal and say its the culprit. Even in the qjet situation i knew my float wasnt cclosing All the way due to dirt. But i did not expect to find "calcuim" or corrosion caked onto the fuel resivor and all the parts that sit in it......

What is the metal the parts that corrode made of?

 

[leroyd92]

Brass and aluminum. Or whatever pot metal they made the bodies out of

It's what the pot metal is made of that the water is corroding. Probably zinc.
