<VV> Maybe the starter.

[Hugo Miller]

I once had an old redneck mechanic try to convince me that wooden 
clothes pins (or clothes pegs in England) clipped on to the fuel lines 
would cure vapour-lock by acting as a 'heat sink'. I tried to explain 
that wood would make a very poor heat sink. Then the penny dropped - 
what the clothes pegs were doing was acting as an insulator, keeping the 
under-hood heat away from the fuel lines. So he was right in a redneck 
kind of way.
