Re: 1275 timing and Dellorto sidedraft

[David Christman <dpc@ai.mit.edu>]

You will get the best power when ignition is timed so that you
are just below detonation at higher rpms (3000 - 6000) at full
throttle.  At this point the distributor should be at max advance.
I usually test this going up a hill.  Don't worry about being right
on the edge as a couple degrees here won't make that much diference.
But the falloff is nonlinear so stay close.

If you have problems at lower rpm the advance curve of the distributor
is suboptimal (assuming everything else is in order.)
