The plain aluminum cylinders used in the Vega and the Porsche 928 used a
hypereutectoid silicon-aluminum alloy that precipitated crystals of
silicon when they cooled after casting. Mercury outboards used that
method, too, IIRC. Some Power Products 2-stroke lawnmowers used a similar
alloy, but with less silicon. Those alloys are similar to the ones used
to cast pistons today.
Don't most newer Briggs engines use AL
or pot metal block/cylinders?
'Don't know. I seriously doubt if it's pot metal.
