Just to toss in some more info.. when I went about changing a clutch it meant
that my car, and thus carbs, sat in unused gas , indoors for 5 months or so.
When it was all back together the stuff that came out to the fuel filter bowl
looked like yellowish milk. After replacing the fuel I had almost 2 miles
before the car ran like caca. It started running very rich. Took off the
airfilter housing and fuel came out of the carb throat onto the new paint, ate
it just like brake fluid.
I called Joe Curto and he said that if I had been using the car continually
there would likely have been no problem but letting it sit and dry in the
carbs does cause problems.
I won't say it's the ethanol as there are many ingredients in the fuel but I
have NEVER seen 5 month old fuel in a closed system look that bad nor have i
ever seen it take off new paint, clearcoat, color, epoxy primer right down to
bare metal.
