<VV> Setting the idle

[Stephen Upham]

The meter has cables that clip onto (around) the spark plug wires.  I  
assumed that the tach could be measured by clipping the #1 spark plug  
wire.  The other measurements were just an afterthought to see what  
the readings were.  I'm a teacher, not a mechanic or electrician.  As  
far as vacuum leaks, I'm at a loss here to know exactly where to  
start.  I can tell you that the tubes to the vacuum devise on the  
chokes are new, the plug for the vacuum nozzle on the left hand carb  
is in place, I have the tube that connects the carbs to the tranny  
connected with hose clamps at the carbs and the connection to the  
tranny, and I am using the thicker 1/16 ? gaskets (2 each side)  on  
the carb bases (plus the insulator of course).  I also have the  
vacuum advance secure.  Where do I start?  Am I measuring the tach at  
the right place using the correct method?
