As the Mallory owners know, that distributor offers the option of a
set of different colored springs of varying strength and length, along
with a nice graph that charts out the advance vs RPM. Pick your
spring to match what you want. I have done exactly what Richard
suggests - advance goes from zero to full between a few hundred above
idle, and 3,000 RPM. The actual amount of advance is dialed in
separately through setting the advance limits on the base plate.

Just a note of clarification on my previous post, I was not referring
to disabling the advance, merely timing the engine to give the desired
amount of full advance at speed (3000 to 3500 RPM). You can easily
start the engine, but because the engine (on the track) never gets
below 4000 to 5000 RPM, the "advance curve" is not an issue. On the
track, you are always at full advance. Why go through all the work of
getting a distributor dialed in with the correct advance curve, if the
engine lives at full advance?......This is for a race engine, a street
engine is an entirely different matter.
