Re: Advanced timing Questions

<< Do I adjust the fuel mixture first and then the timing? How about the idle 
speed?>>

On my '78, you can adjust the fuel mixture before or after the timing.  These 
are two mutually exclusive events.  One does not effect the other, directly.  
The idle is important because you want to stay at idle(~1000 rpm) so that 
your centrifugal advance doesn't kick in and change your timing.  As you 
change your mixture or timing, the idle will vary.  You want to adjust your 
idle screw to keep the idle correct.

<<To what should I advance the timing so that I can return to the peppiness I 
enjoyed.  As well, I will be installing an adjustable cam sprocket.  
Advancing this would do what and what would retarding the cam do?>>

All things being equal, when you retard you cam timing, you will feel your 
power band  shift towards the higher end of the RPM range and in turn you 
will feel less on the bottom end.  Advancing the cam timing will shift the 
power band down with a loss in the top end.
