Brian-
Maybe it will help to fully understand the front mount distributor and the cam and weights aren't the issue you seek. The FORD Front Mount Distributor is the 2nd most misunderstood faction of these old Fords. #1 is the 6V/POS GRN Electrical System. Take note of my post below from Tony in TX about the front mount and setting the points. You must first have a GOOD set of new points to work with. The STANDARD IGNTION/BLUE STREAK p/n FD-6769X, set is the best. ECHLIN, p/n CS-35 used to be as good as but now are made in the land of the Chi-Coms and are junk –they cannot be set and timed correctly. Both use the original phenolic rubbing block whereas all others made today use a plastic rubbing block. You can get them at NAPA but avoid the ECHLIN. Be sure you have all the required manuals to use as a reference. The manuals have the original timing method with the ¼” offset rule but there was a guy that made a handy setting gage which made it quicker and easier. Don’t’ know if he still sells them though. Also, get a copy of “75 Tips for N-Owners” by Bruce(VA) as he has a method of setting the timing and testing before you mount the unit. The biggest mistake folks make when mounting the front mount unit is to get it 180° off location. You will observe the male cam tangs on the unit are offset. Likewise, the cam shaft on the engine has female offset slots which mate into the tangs when unit is mounted correctly. If one forces the unit down off location when bolting to the engine, the second power is applied the unit will attempt to orientate itself but it’s too late and the aluminum base will break and bust up –see pictures below. The base is junk then and many do not notice this. You need to get a new base and just swap out all the guts. Remove your unit from the engine and see if it was ruined from incorrect mounting.
