Well I gather you did do the test today...
otherwise you would have seen it moves in
relationship to the cap
EDIT
I was gonna run the test today.. I just fired
up my Rampage so I was gonna do the test.. but
I only have 1 dist that will advance and its a
adjustable thats locked out.. I was gonna change
it but I dont have any heavier type springs.. the
ones in it would be full advanced by idle rpm which
is what I use to use in my other engine.. but this
engine is injected and likes the locked out dist so
the computer does the rest.. I'll look a bit more
tomorrow to see if I have a decent dist.. if I do I
will pull the one in the Rampage and video the test..
I was gonna start it with the timing light on it and
mark the back edge of the rotor as seen by the light..
then start increasing the rpm.. the whole time with the
light on it.... wish I hadnt sold my dist machine
it would have been much easier to video on it
