Now I'm getting to understand more sbout the timing/distributor system I have
some more questions.
I understand that the centrifugal advance system on the distributor advances
the the timing depending on the revs. What does this do in terms of power?...
I understand it is meant to increase fuel effiency. I also understand that
you can't have full adavance permanently ( like a race car) because of poor
idle. But WHY does a lot of advance work at higher rpms (it must be something
to do with when the *bang* happens in the cylinder).
The reason I ask is becuase I've been toying with the idea of putting lighter
springs in a distributor so say max. advance will occur at around 2500 to
3000 rpm. It currently occurs at around 5000 rpm in the Midget? (at 37deg).
I've been lead to believe that this will give my car more *snap*
of the line (more power at lower rpms). Note: it's an unmodified motor
in all respects.
Why will max. advance at lower rpms give me more power? What happens if I
lower the max advance to say 35deg? (I understand with the 1275 motor,
37 deg is the max amount of advance possible). Note: I only use premium gas.
Obviously there is a point at which more advance in the timing has no effect
or even a detrimental effect.
Lots of questions!
Cheers
Marcus
