Thanks Paul Yaw
 Since I sent out that e mail regarding rough running and plugs, I found
out from Tracy that I have my ignition timing over-advanced @ 30 BTDC at
5000 rpm. I apparently misunderstood the 30 BTDC at 5000 rpm for
Ignition input to Tracy's CPU as being the spec for setting the spark
via distributor position.  Don't know if the overadvance will eat plugs
faster, but may account from some of my lack of power.  Tracy recommends
23 BTDC at 5000 rpm so don't know if 7 Degrees difference will make any
significant change in power produced or not.  But, will reset the timing
this weekend and check the plugs. I have the stock plugs as well as the
NGk B9EGV series, so no problem to stick the stock ones back in.

BTW the subject of vacume advance came up awhile ago and Bill Freeman
forwarded
some comments from Gary Hertsler to the effect that additional advance 
does not help below oxygen altitudes. I talked to Klause about it
and he said Gary Hertsler only had one of Klause's ignitions 
and one fixed advance mag therefore the average advance was not 
changing fast enough with altitude. If Gary  had two electronic 
ignitions he would see different results.
