I have a Sears timing light and I think it (or any other model) is a
handy and worthwhile tool to have around. But then I think that about
most all tools. It makes timing an easy task such that I probably
check/verify the timing at least once a year. There is a collar of sorts
on the distributer with a bolt that clamps it on. You just loosen it
with a 7/16" wrench so you can rotate the distributer until the timing
marks line up using the timing light.
You don't really need a timing light though. For at least five years or
so of my initial MGB ownership, I just timed by making adjustments with
the distributer position and then driving the car until I got it to
where it had the best idle and acceleration. I also tried what is called
a static timing light which essentially checked continuity of the points
when rotating the distributer but that seemed to only be good enough to
get the car close enough to start. I still ended up doing the road
tuning method afterwards. The timing light just eliminates a lot of
trail and error.

Subject: New distributor
So I bought a new distributor - which has its own interesting points.
For example, there is no vernier on the new distributor which leaves me
to wonder how best to adjust the dwell.
Also, please correct me if I am wrong (it's been so long) but I change
the timing by loosening the distributor and rotating it. Correct?
Lastly, is there a alternate method of getting a good timing adjustment
short of a timing light?
SEARS wants $65.00 for a timing light, which I don't mind paying if I'm
going to use it often.
