Lotus Elan

I am pointless!

PostPost by: "Paul Adamson" » Fri Oct 29, 2004 10:10 pm

I've just replaced the points and condenser in my Elan's distributor
with one of those popular Igniters.

Fitting is was easy.
The wiring is simplicity itself.
The components look well constructed and all the parts fit well.

I noticed one other thing. There is now more ignition scatter around
idle.
I half expected this. I had guessed beforehand that the heel of the
points set would cause some drag on the distributor and it looks like
this drag take some of the play out of the system.

Now, without the points, and at low rpm. there's more wobble going on.

Has anyone else notice this?

Now, I have two more questions.
Q1. Do you think that the advance curve will have changed in any way
with the removal of the points?
Q2. While the specs for the ignition timing are specified at idle, does
anyone on the list work from the other end?
i.e.. Does anyone set the ignition timing at e.g. .35deg. at 4000
rpm and ignore what advance that gives at idle?

(Snip)...

There is now more ignition scatter around idle. (Snip)...

Eliminating the points usually reduces the amount of scatter in a good
distributor. If yours is now showing more scatter, the distributors
bushings are worn.


Q1. Do you think that the advance curve will have changed
in any way with the removal of the points?

No, the advance curve is controlled by the flyweights and springs.
Installing the Ignitor doesn't affect them or the advance curve.


Q2. While the specs for the ignition timing are specified
at idle, does anyone on the list work from the other end?

Setting the static timing at full advance/ high rpm is the more accurate
way to go, but less convenient. I usually do that initially and make note
of what idle setting results. Then use that value to quick-check the
timing at idle in the future.

wouldn't the heel of the cam drag on the cam,opposing the spring/bob weights?

Static timing is only a starting point to get the engine running.
Ideally the timing should be set up on a rolling road as you can usually
get a few more degrees advance from the safe settings in the manual.

Checking the advance at 4000rpm is a good way to make sure the dizzy is
working.

Sounds like the dizzy has worn out and needs a refurb. Try H&H or Aldon
for this.
