Super C zenith carb

I put a brand new zenith carb on my Super C over 3 years
ago. Last week end I went to unload it after a tractor pull and it
would not start. I finally got it run long enough to unload it and
the fuel was pouring out the bottom of the carb. I pulled the
carb apart thinking there was something stuck in the needle
and seat. The needle looked good. The seat had something in
it. I took it out and the bottom side was completely corroided. It
was from the bottom of the seat all the way up to where the
needle seats. I have run probably 15 or 20 tanks of gas thru it.
I guess the ethenol finally caught up with the brass seat. Oh
for the good old days of leaded gas.
 
Wasnt the ethanol as ive been burning it for 40yrs and never had a carb failure yet blame it on something elxe.
 
Heet or any alcohol base additive will eat and corrode aluminum, that includes ethanol. Burn high test gas will help in most areas(not all)
BTW you might try to repair it with a gas tank repair kit for steel tanks. Available at just about any auto parts store.

Really?? If that is true, then the aluminum carburetor on the Ford F100 I used to own should have been totally dissolved by the time I parked it because the body was falling apart. It ran on E10 for at least 25 years.
 
I remember having a push mower years back that would not run and the inside of the carb was totally corroded like that. No ethanol then
 
I put a new Zenith carb on my Super C probably about 12 years ago, always fed it e10 gas, never had a problem, best money I ever spent on that tractor
