Aha! Are you sure you dont have a vacuum RETARD on that dizzy? Depending
on the year (I don't remember your year), the 45DE4 dizzy had a vacuum
retard on it. First thing you should do is disconnect the vacuum
totally, plug the line, and set the timing for 30-32 BTDC max advance,
or about 12-14 BTDC at idle if you don't have the adjustable timing
light. See what happens.
BTW, if you have a Bentley manual, you can look up the advance curve in
the front section of the book. It'll also tell you if it has a retard or
not. Most of the retard dizzys were set at 2 degrees ATDC, so if you
have a nice cam in there, throw out the vacuum and just use the
mechanical advance.
If you don't have a Bentley, post the numbers on the side of the dizzy
and I can look up the specs for you later tonight. You'll see 45DE4
##### WWYY.
##### is the Lucas part number(like 41808, for example), and WWYY is the
week and year of manufacture.

Subject: Re: car runs need help further update
I used a Lucas
OPUS dizzy (stock EI unit for the car) and left the advance
curve/springs/setup
stuff as it was, just took out the old timing pickup and etc. and
installed
the crane stuff. As I've noted before I can see the advance move by
sucking on
the tube but can't suck hard enough to move it all the way through its
path
(but it will go if I do it with my finger). Don't take this the wrong
way, but
I can suck. I'm a (sh*tty) bicycle racer.
So I guess my questions are:
has anyone had luck with this setup (stock curve, etc.)?
does it sound like my advance is working right?
Thanks!
