Recently patrickt has brought to memebers attention a problem with "Holley zink ethanol clogs.
This is new: stumbling/missing at idle/cruise speed.
I thought that aluminum carbs were not in danger of the problem with these fuels. I checked my Holley manuals and couldn't find anything on the issue and then read Edelbrocks manual. Under the title
Blended Fuels they discuss the two types of blended fuels, gasohol and gasahol. They describe that gasahol can be a blend of gas with either ethanol, methanol or other alcohol. They go on to say that "methanol blended fuel should not be used in their Performer carbs" and I guess the rest citing, "it will cause corrosion". " It can cause rapid failure of seals, gaskets, diaphrams and pump plungers."
Is this a bigger problem than we thought. Are there any experts that can shed some light on methanol blended fuels and what areas of the country are using methanol blends. I don't think gas stations are specifically stating on the pumps if the blend is methanol or ethanol.
