    Re: Checking the condition of my distributor

    With the Breakerless SE system there is NO touching to effect switching. The 'triggering' is done across a healthy air gap via Hall Effect. A set of vanes are mounted to the bottom side of the overhead centrifugal advance via the rotor mounting screws.

    The vanes pass through a rather wide 'slot' in the trigger module that mounts to the breaker plate in lieu of conventional points. The system is HIGHLY tolerant of distributor shaft wobble... That's one of its design attributes.

      Have you thought about having your distributor restored and / or run on a distributor machine?

      Joe,

      I am going to have it restored and run on a machine. I just wanted to see if I could diagnose a problem now. You know just messing around in the garage

        Re: Checking the condition of my distributor

        I pulled the cap and rotor button off and checked the shaft play. From side to side the shaft seems to be in spec but the up and down play seemed to be about a 1/4" which seems excessive. Also the springs that are on the distributor are very old. I put them on in 1993 and have no idea what tension they are. I do have a few new never springs laying around but I dont know which ones to use. They are diferent colors. Does anyone know what color would be stock?
        I bought a dial back timing light last weekend so probably will be experimenting with mapping my timing this weekend. Any tips on what to do next is appreciated.

        Thanks as always...this board is awesome.

          OE springs were all natural finish steel, so your color coded springs are aftermarket.

          Use the lightest springs first to get the centrifugal in ASAP and set the initial timing to get a total of 36-38 degrees.

          If it detonates, install one heavier spring, and continue installing one of the next stiffer springs until it doesn't detonate.

          You can set up the curve on the car, which is actually better than a machine, because you can't test for detonation on a machine.

          Your end play is WAAAAAAAAY excessive, and you should overhaul/blueprint the distributor. Seach the archives. It's been discussed many times.
