<VV> [FC] Carburetor Heat System

[Bruce Gwyther]

  The winter/summer plate is for the  opening under the gen/alt and near the 
oil cooler.  The cylinder baffles fit under the cylinders (and required for 
proper cylinder cooling).  The deflector/baffle plates we are talking about 
are located on each side of the engine compartment at the opening to the 
fenderwell and subsequently to the air intakes on the sides of the body. 
They are  'almost' triangular in shape and redirect the incoming air.  As JR 
said they reduce carb icing in colder climates but are not needed in warm 
climates.  The summer/winter plate allows some hot air from the drivers side 
of the engine to recirulate back to the top of the engine or exit out the 
back. It may help with carb icing, but not very much (especially on the 
passenger side carburator).
