1st:  At a low Idle (600) it has an occasional kick, stutter  etc.  With the 
RPM up around 1000 it's smooth.

2nd:  Between  2000 and 2500 RPM she seems a bit rough,  above that she 
smoothes out and  runs fine.



Hi Jim,
I know that you said the timings been checked, but here's what I suggest. 
 
Temporarily disconnect and plug the VA and see if either of these two  
conditions change.
 
Connect and watch the timing light to see if #1 above can be caught that  way.
 
#2 seems to occur about when the centrifugal adv is all in. Could the  
weights be bouncing around at that point?
 
If not with either trial, swap for known good carbs.
 
Good luck.
Regards,
Bob Helt
