While working as the chief restoration engineer at the Fort Lauderdale Antique Car Museum this past summer where we have 39 Packards, I came across a 1934 Packard Eight, 5 passenger sedan that had not been running in a number of years. Examination of the distributor revealed that somone in the past was not able to get the engine into correct time and they tried to remark the distributor attempting to get a different firing order to function. Obviously this did not work and so I dug into it. With the distributor cap removed and number one piston at top dead center, the rotor aligned with number 3 piston instead of number one. This is a dual point/coil system and so the opposite rotor tip was aligning incorrectly as expected also. My initial thought was that the valve timing chain had jumped a tooth due to wear and so proceeded to disassemble the front end but the timing chain was found not to be sufficiently worn to cause our valve timing problem. I also, verified the valve timing by rotating the crank by hand and noting the position of all valves. The problem was therefore narrowed down to only spark timing. At this time I knew that the drive gear on the camshaft was probably not correctly aligned with the distributor drive shaft but to get at this gear means separation of the cylinder casting from the crankcase casting, a non-trivial job! So, here was my solution: First, I verified that the distributor itself was not to blame by comparing it to a NOS unit Fred at Max Merritt sent me. My existing '34 distributor was exactly the same as the NOS unit. Therefore, I began to think of ways to modify the distributor. I heard stories from my Packard Club associates that they had heard of twisting the distributor drive shaft in order to properly align the rotor. Not wanting to do this, I un-pressed the spark advance plate from the internal distributor shaft, rotated it 45 degrees CCW and re-pressed both piece parts back together. This did not affect the opening and closing of the points and when the engine was first cranked over, it fired immediately and ran as smooth as a baby's bottom!
