Healey 3000 distributor drive gear spacer washer, end float!

I'm rebuilding an engine that was re-built by the owner back in the 80's and have a question concerning if there should, or shouldn't be a spacer washer under the distributor drive gear, pt# 021-315.

The spacer was found installed on the drive gear when I dismantled the engine. But now when re-fitted with the distributor housing bolted in to the block with a paper gasket and the three bolts holding in place, the assembly binds up to the point locking the cam and causing the engine not to rotate. When I slacken the bolts everything rotates fine.

On some British engines you have to set end-float by using various shims, is this not the case with this engine?

John,
just finished building three BJ8 engines, none of them had washer or spacer. There is a thick spacer on the oil pump drive

I Have observed a copper washer between the dizzy drive fitting and the aluminum dizzy housing probably to eliminate housing wear. However, in all cases the clearance was no more than a few thou. It did not appear that any tolerance fitting was required?
