timing quirks; and other sundry

[Huw Powell <human@nh.ultranet.com>]

I took the timing light to the sorta-tweaked cammed coupe tonight, it
showed I was basically at 6 deg BTDC with lots of power.  Advanced it to
about 15 or so, remixed, it is a bit smoother but has lost a bit of
torque and some high end pull.  Going back tomorrow... 

Question - when measuring it, esp. at the 6 BTDC the mark would
fluctuate, almost in time with the OXS cycle, to points about another 6
degrees or so ahead.  It didn't seem to do this at the more advanced
setting.  This is with the dist vac adv hose pulled.  Answers?

Has it occurred to anyone that using the brakes on a vacuum assist car
will momentarily lean out the mixture as the vacuum is replenished from
the intake manifold?
