Hi all from Hot and Sunny Queensland (43 c at the moment) I am carrying out a few timing experiments on my Comet, fitted with a BTH Electronic Mag, can anyone tell me where I can find the advance curve for a BTH?
In case I have the wrong terminology: I am looking for a graph that shows changes in Timing Advance against engine RPM.
My other question is, I don't have my new Tacho yet (and can't find my dwell tach meter) so can anyone tell me an approximate value of RPM, at idle, for a well tuned standard Comet, before anyone jumps on my head, I do realise that this is a variable but am only after approximation...i.e. 500 - 700, 600-800, 1200-1400 etc I will get down to fine details once my tacho arrives.
Thanks and regards
Kevin Dennis
