[QUOTE="Martyn Goodwin, post: 51284, member: 2433"] This is getting confusing. Here is the ignition curve on the Pazon system I purchased for my Comet. And I have checked with Pazon and they have confirmed that it is what the system they supplied to me should actually be doing. [ATTACH=full]2376[/ATTACH] Now the rub is when I installed the Pazon late last week , in place of the rebuilt magneto I experienced a "seat of the pants" reduction in bike performance. So I tweaked the distributor position , moving all points towards further advance, yielding a start at 6 BTDC and full advance at 32 BTDC. But I must say that even with that change, I thought the magneto gave superior performance. So the original Lucas magneto is back in the bike with the ATD modified so I have 4 BTDC at zero engine speed and 32 BTDC fully advanced. FWIW both the Pazon and the magneto give first kick starting.
