A couple weeks ago, I posted a question on adjusting timing on a 9N distributor. I had to return it because I could not get the ignition timing set properly. It was close enough all the way at its limit but the coil's pigtail spring wouldn't reliably contact the concave brass screw in the distributor. I would appreciate any leads where I can buy a "good quality" distributor. There are no longer any Ford/New Holland dealers near me anymore or I would get an OEM unit if they are still available. I can't rebuild my present one because several years ago, the distributor loosened up and broke one of the mounting ears. I had it welded back together, it bolts onto the engine OK but it is not perfect and cannot be timed to specs and the tractor is not running to its potential.
