<VV> Engine pre-oiler

[Ron]

After major maintenance or storage, the carburetors are dry and the engine 
needs to crank for a while before it will start.  During this cranking, it 
will attain full oil pressure and be well pre-oiled prior to starting.  Just 
let nature take it's course and everything will be alright!  But, don't 
prime the carbs.
