    Bushing(s) bad.............had that happen a few years ago.

    Didn't know you had this problemo.............check the rotor if it is wobbling up top you will know it quickly.

    Stuck advance weights? Check that the terminals aren't hitting the rotor. If the cap terminals are loose, the inside pieces that conduct to the rotor can and will hit it, and bend them out of the way. You can tighten them up if loose pretty easily.

    Check your advance weights and springs. You can get a new weight and spring kit for about $5.00. I can't think of much else that would cause it if the bushings are tight.

    Should be two arms 180 DEG from each other under the rotor. One side of the arm is attached by swivel pins the other side is attached by springs. They controll some of the advance via centrifical force. The more RPM the more advance.Good look, and good bowhunting.

    did you pull the cap and rotor off and observe the two weights? All you do for a "test" is make sure the little bushing they slide on is present and not damaged, and that you can move the weights easily (spring pressure on them) with your finger. Make sure there are two springs as well, maybe one came loose.

    A bad vaccum advance will be most noticable under accelleration. A flakey pickup could also be causing you weird problems. You could also slide over to U-pullit and pickup a whole working dist for about $15.00 if you get tired of playing with it [​IMG].

    Vac advance is pretty easy to test. Pull off the cap, remove vac hose off carb, and suck on it, watching the rod the vac advance pulls on, move. Once you get it to retract, plug end of hose with tongue, and watch for the rod to move. if it moves, the vac advance is bad. If it holds position for a few seconds, its fine. As to noise, I really doubt thats the problem. replacement may be an idea, or just pull the distributor all the way out, and see if the shaft or gear is shot or worn out.
