Default Just finished off Lars' ignition kit.

Had the thing half-donkeyed for two years, just pulled the distributor and fixed the slop. Had between .018 and .023 for the shim, so stuck a .020 shim in and it was nice, all the slop was gone. Car feels much smoother. Used the stock weights with the gold springs.

Question: What are the benefits of shimming the distributor? Does it just decrease variance in the advance?

:eek: Excessive distributor endplay can also cause cyclonic variation of the photonic erg-wave energy distribution. Resulting in excitation of the K-shell valance electrons increasing the mass deficit of all exposed molecules.:jester

Yes a valid argument for distributor less ignition. :rolleyes:

Easy for you to say. :D

You forgot about the differential variance in your flux capacitor! :jester

Short answer : Yes
:cheers:
Long answer : The first response may have been accurate to the 4th power but did not allow for the variance in the alcohol content of Beer from weekday to weekend in various states of the US.

Steve - you must realize that the end play on the distributor shaft can cause
a variation in the advance - due to the spiral cut in the gear. I don't know if it
should be of too much concern, as several mils can't vary the advance by
much more than a degree. Of course - excessive play may cause premature
wear of the bushings and gear.

So - did your overhaul of the dist give noticable improvement ?

Hard to say. Not really is the best answer, I'd guess. I got rid of a flat spot in the powerband, but I also changed the fuel filter at the same time. Picked up a little bit of power below 2k also it seems, probably because the timing had slipped from 10 -> 25. *sigh* I need to invest in an adjustable timing light for myself so I can keep these things under control.

Lars has a good writeup about how to adjust your total advance without an adjustable timing light as well. Basically, if you measure the circumference of your balancer with a cloth measuring tape accurately as possible, then divide that measurement by 10, you can measure back that much from your 0 degree mark and scribe a 36 degree mark. I have an adjustable timing light that I'll use myself, but I thought that was wicked clever when I read it...

S, P, D,F.

I am king of geeks. :p:
Well no, they begin S, P, D, and F, which were named for the "Sharp", "Principle", "Diffuse" and "Fine" spectroscopic lines, but after the F orbital the quantum azimuthal numbers are labelled alphabetically, so following F comes G, H, I, and so on.

You have been dethroned. ;)
