[QUOTE="Howard, post: 25447, member: 271"] [b]addition[/b] OK TT wait til I've reached a conclusion, and I'll have a shot at measuring where it's firing. David, I'm only on single plugs. Peter Appleton says he's running 40 degrees on a more sophisticated ignition computer and thinks he could go higher, and if the timing marks are right, I've past that and still going. My thought is, why do conventional systems stop advancing at 4,000 rpm (ish)? Why should the advance be the same at everything over 4,000 rpm? Could it be that there is such a wide range on my advance curve that I can keep advancing it to suit 5, 6, 7,000rpm but not be over advanced at lower rpm? I don't know. All I know is, based on the Pazon timing mark I'm running at 43 degrees, and so far every advance has made a perceptible improvement. Watch this space. H ps Just wait til I get to 60 BTDC - that Ged Abrahams won't be coming past me next year !!! ;-) [/QUOTE]
