As many of you know I am in the final stages of building a "fast street" engine
(whatever that is). After installing the cam in my reworked block I cleaned
the gear that meshes with the cam, drives the oil pump and the distributor
(spindle assembly) and bead blasted the timing chain sprokets. It looked fine
but just in case I showed the spindle assembly to my expert friend. The gear
looked good and I planned to re use it when my friend pointed out that gear to
shaft pin was loose which allowed the shaft to rotate on the gear. Since the
shaft drives the distributor from the gear it seem to me that this slop would
cause some variation in the timing on both the advance and retard sides and
could be the source of a mysterious timing problem usually attributed to a worn
distributor.
Since this is, at least to me, a place where I would never have thought to
check for a timing problem I thought it might be interesting to my friends on
the six pack net.
