Boy!  Do I agree with this, but for a different reason.  I run a Y.S. 
1.40L and for years I was reluctant to run the engine dry.  I leave my 
airplane in my van all the time and I discovered that, in the summer 
heat, the conditions inside van caused the fuel in the line next to the 
carburetor to evaporate, leaving almost pure oil at the fuel nipple.  
Sometimes it was so thick that I had to remove the fuel line from the 
carburetor and 'milk' the slug of oil out of the line, before I could 
get enough fuel in the engine so it would start.  Taking John Fuqua's 
advice, I started running the engine dry at the end every flying 
session and have never had the problem again.
