Carbs Damaged By Blended Fuels

How appropriate. The only 3 stations in Kalifornia that offer it are right down the highway from Sucramento, the nerve center of Kalifornia regulations and the most stringent "clean air and clean fuel" lobby in the entire country.

Great site though and thank you for referencing it.

I had to replace the metering blocks on my Holley because of corrosion. I buy all my fuel from either 76 or Chevron stations as well. I am sure the ethanol was the cause.

Just on a side note: In Europe there are 4 different gas selections, high-mid-low grade and blended fuel (ethanol). Even the blended fuel is less expensive, hardly anyone buys it. They consider to remove the "4th class) fuel from the market.
The European fuel has higher standards than the US, besides that there are 14 (!!!) different fuel standards in the US. Not including the 3 grades. Depends where you live and buy gas it is different.
The additives in today's fuel are in there to make the fuel stable - at least for a short tim, because there are so much junk in there.
I buy race fuel, Sunoco 260GT, from time to time for my 2-stroke engines (model airplanes 50-180cc). This fuel has no additives at all, it is the fuel like we know from the 70's. It vaporizes without residue and has a very clean burn and it does NOT stink.
What I'm saying is, if I had a vintage power plant or carburetor setup I would do one or the other
one - add water to the fuel shake and freeze it, you remove the ethanol with the frozen water. Been there done that - not very "nice".
Or-
two - buy race gas (some marina gas too) for $8/gallon and do not ruin my high dollar engine.
