I have a 1972 Fiat 850 Spider that is new to me, and running poorly. The spark didn't seem to advance so I bought a brand new, but slightly different. With new:, cap, rotor, points, condenser, mech advance, it seemed like it would remove a lot of potential problems. It was only $90 plus shipping from Slovenia. It arrived today.
I positioned the motor with #1 cylinder at TDC, noted the position of the rotor and removed it.
I inserted the new distributor (with good preset point gap) at what I thought was the same rotor alignment.
The cap, however, points the opposite direction. So I spun it about 180, but that required a few longer wires.
It wouldn't start in various positions.
I then pulled all of the plugs, cleaned and regapped them. Each plug produces a a spark on each wire.
So, all I can think of is I'm off a spline or 2? Does that even matter if the entire distributor can spin to any position (other than lining up the timing mark on the pully and case.)
