Re: [Amc-list] Performance 195.6! ignition timing.

[Tom Jennings <tomj@xxxxxxx>]

Welp hacked the Delco distributor for maximum centrifugal advance. Let's 
just say this is not destined to be a performance part. I got probably 
20 degrees from it, rather than stock 11. Should be pretty good.

I drilled the travel-limit hole out to 33/64ths. The weights clear the 
housing by .010", plenty. What I neglected to eyeball before hand was 
that the cam assembly that does the advancing couldn't incresae retard 
as much as it increased advance; complications of the shape of the 
weights and the cam/lever. A deeper nick in the tips of the weights (a 
tiny fraction of a gram) allowed absolute maximum travel.

I don't have a good way to measure angular displacement so I'll have to 
wait until it's assembled. Should at least be a big improvement.

Since I'm running 36 degrees total advance I will check a plug or two in 
the morning for detonation, but the gas pedal is nice and light, and 
vacuum is high at cruise.
