Problems ethanol causes in vintage cars?

StrokerScamp, I got out of small engines before Tecumseh forgot how to make carburetors. Even so, removing the fuel bowl and flushing the line through by letting the float drop was pretty standard procedure for getting a Tecumseh engine running after prolonged storage. I imagine the double-whammy of cheapened carburetors and d'ethanol in the fuel pushed those engines well over the headache line and into practically unusable territory.

I didn't think much of the plastic carburetors Briggs & Stratton put on their cheap 929s in the '80s, but maybe that material would be more d'ethanol-compatible than cheap potmetal. Donno. As I say, I got out of it. Wish I'd kept my nice 6B-S with windup starter, though.
