I have a 1953 ford Customline with a 215 inline 6. So for the past few months, I have been trying to trace a down a noise, that seems to progress worse when the car gets up to speed at about 50 55. The noise sounds like a fluttering noise. I have new points, plugs, wires, cap, rotor. The carb has 20hg's of vacuum. I did a compression check with 120 per cyl. So distributor gurus, The distributor is original and I was wondering if there should be any freeplay in the the shaft up and down or side to side. There does seem to be a mill. of freeplay from side to side, but up and down on the shaft, there seems to enough freeplay, to where you can here it making a clunking sound. You can also see the freeplay when you pull up and down on the shaft. I did take notice also that a few months ago I put a new rotor on and notice that a chunk of the metal part of the rotor was broke and replaced it with a new rotor. So all said and done is this creating my points to float and misfire creating the fluttering sound? If this is the cause should I have my distributor rebuilt or buy a new one? Thanks fellas.
