balancing timing and fueling...

[ae1969]

From this assumption, I reason that if I use an exhaust gas temperature gauge, I can lean out untill I notice an increase in exhaust temperature, and then try to ad some more advance and see if this reduces the exhaust temperature.

If this is successfull, I can then try and lean out a bit more, and advance accordingly over again, untill at some point I run in to missfiring or exhaust temperatures that can't be brought back down through ignition advance.

That is exactly what I did for part throttle/cruising..........
