Sorry, I posted this earlier to Buy/Sell by mistake,
I have been told not to use alcohol based unleaded gas in my old lawn-mowers, weed wackers, etc, because it causes damage to o-rings and gaskets.
Does the same warning pertain to older mopeds.
I have a 1980 Sachs Commuter moped with 49cc 2 cycle engine. It runs perfect and thought maybe cleansing ability of alcohol base would keep it running that way
