<VV> Distributer shaft

[Harry Yarnell]

I havn't heard about the loose point plate pivot pin in a long time. This
used to be chronic years ago with changing dwell, hence changing timing.
Check it by trying to move the point plate radially (in-out) with your
fingers at the advance link connection, or by moving the whole points assy.
radially. There should be no play.

As long as the roll pin is still there, and it sounds like it is, it should
be fine. I think mine has more up/down play than that, and it's fine. My
timing doesn't wander or anything like that. When the engine is moving, the
force of rotation will "push" the distributor shaft so that it won't move up
and down. What you really need to look at is if the timing wanders, that can
be caused by number of things - lateral runout in the shaft, weak advance
springs, loose points plate, etc. Hook up a timing light, at idle your
timing should never change.

For uneven idling, check your linkage if it's a dual-carb setup. if one side
is bound and holding the throttle plate open a little you can get a bad
idle. Check your ignition wires/plugs.
