Thanks for all of the responses. I=E2=80=99ve used this distributor in =
another block, and this is the first time in the =E2=80=9Cnew=E2=80=9D =
block. In the old block I had the correct clearance without shims so I =
think you are all correct in that I need a new bushing in the =
=E2=80=9Cnew=E2=80=9D block. The bushing didn=E2=80=99t look obviously =
worn but I guess looks are deceiving!
=20
Thanks again, FOT is great!

Hi - if the bushing is worn, it needs to be replaced. I would not run =
the gear with a thin shim under it, the shim will not last. I just =
looked at Moss and they have that distributor bushing listed for $75 =
plus or minus.

If you have slop with that distributor drive, you will never get the =
ignition timing to be rock solid.

On page 1.130 and 1.131 of the Workshop Manual it describes the =
procedure for obtaining the correct clearance or float for the =
distributor gear driven by the camshaft. It gives two scenarios: one =
where there is interference of the gear and the bushing; and a second =
where there is not enough clearance or float. What it doesn=E2=80=99t =
consider is if there is too much clearance between the gear and the =
bushing. That is the case on my TR4 engine. I had 0.016 clearance and =
added a 0.010 shim under the gear to get the desired 0.006 clearance. =
Has anybody else had this experience? And what did you do about it.
