In my never ending habit of doing first things last I decided to
give a shot at checking the timing on my Ambassador after my eight months of
ownership. It has always had a slight ping at low speeds so I figured maybe
the timing was retarded a bit. Checked the points which were set fine. So I
need to find 2,200 RPM to check advance. No tach just a Speedo. So I break
out my 20 year old engine analyzer and hook it up from memory as the manual
has long since left my ownership. Red positive, black ground and green to
the coil to distributor wire. So I have settings for 4, 6, or 8 cylinders
and well what do I use? The setting for 8 appeared to be close but is there
some kind of math involved in using this thing on a 2 cylinder vehicle?
Anybody know settings or any conversion needed to do this? I did manage to
get it to not start for a while and then found a 'sweet' spot where it seems
to run a little better than before. But I would like to get it right. Should
I go seek out a new analyzer or does someone know how this works. Next
question is how do you guys hold the RPMs steady while holding the timing
light in the cramped position behind the front wheel and turn the
distributor all at the same time by yourselves?
