Hi,

I have a couple of aging (15 years plus) two cycle engines and neither 
has suffered any fuel system or corrosion problems.  The third two-cycle 
engine is a few years newer but has likewise not suffered from that 
stuff in *all* the gasoline available at the gas stations. How many 
decades in the past were those engines suffering from this corrosion?

73,
