Distributor Drives

[Martin Benade]

Each engine had a pair of R or L distributors, not one of each?

[Jacques Lefriant]

Yes Martin
but you could put one of each if you had one fwd and one aft.

Be sure the number one post on each distributror cap is pointing at eachg other. Alan The Stable.

Hi Alain
that is true for the 90* drive for the 60* they point aft.

And why is that Alain and Jacques?
For the curious, it is because each distributer fires 2 plugs on each side of the engine. This is so that if one coil fails the engine will continue to run on all 4 cylinders. You can choose which plugs, fore or aft, which distributer fires. The wire position chosen for each distributer makes the wire bundle a very little simpler with the recommended distributer orientation and probably simplified service back in the day. I choose to have one distributer fire the forward plugs and the other the rear plugs. Orienting the distributers so that the points wire runs as nearly directly aft as possible on a Carrera also helps.

You should not have any of this distributor vibration Stuff as there is a fiber oil pad always pressing on on the points shaft. Alan The Stable.

[Martin Benade]

What vibration are you referring to? An oiled felt pad would squash that?
