Re: 28 Hudson motor puzzle

Unknown

Here's one for Geoff or anyone else with any
ideas.  We have a 28 Hudson with a supposedly rebuilt motor.  Starts
instantly and no smoke or bad noises.  However there is a persistant miss
on No 5 cylinder.  All others fire fine.

Changed the plug  (twice).  No
difference

Pulled the lead out of the tube in case it was
shorting.  No difference

Put on a new distributor cap.  No
difference

Tested compression.  90-95psi all
across

Checked tappet clearance OK

replaced the plug lead.  No
difference.

 

The distributor lobes look Ok as do the
points.  There is about .005 slop in the upper portion of the distributor
shaft.  I have seen worse without problems.

 

Any ideas?

 

Thanks
