Thanks. I thought about the possibility of a 180-degree error in
installing the cap, but there is a single notch on the cap and a
corresponging tab on the base, facing the engine, so that doesn't seem
possible. The little vent on the top of the new cap is 180-degrees
from where the old one was, but in the instructions it says quite
plainly that this doesn't mean anything.
I think that perhaps the marking for Cylinder 1 must be wrong on the
new cap. The old one had no marking at all. It was covered with dust
so I figured there must be a marking under it somewhere. But I brought
it in & cleaned it up - nope.
Thanks for the hint about lubing under the rotor.
