<VV> More ethanol problems - minor Corvair content

[BBRT]

One of the things snow mobile racers do or did, who run straight alcohol, is 
to drain the tank and run on (real) gasoline to purge all lines, etc. 
Grant, looks like with increasing ethanol laced gasoline, the small engine 
repair shops will be doing more business...
