Morning all, hoping that there might be a pool of knowledge on this question - have a 12v BTH FM1C Electronic ignition /Magneto, on a Comet, and looking to time it for good all round road use.
Series C. Without ATD, all advance/retard is down to the chip inside the device, so that's taken out of the equation somewhat. 8:1 Piston, 105 Cams, 30mm Concentric/Premiere Carb -What might be the consensus on setting the timing? -I'm puzzled between 4 Degrees BTDC, and somewhere in the region of 34-36 degrees BTDC (which would be right for an ATD on full advance I believe)? -Help, advice, levity and satirical comments welcomed providing they get us closer to usable answers! Thanx in advance - jez
