When timming by ear, I know cause I have to do it too. Take the distributer and turn it till u find a point where the motor is at it's fastest idle. Retard the distributer just a little, then check it by reving up the motor only a little. About 1500rpm, and pull off the vaccuum tube, and it should idle down some, put it back on to check still more. Keep moving the distributer till it has the greatest RPM ajustment between off and on(vaccuum). But remember not to move too far from the point u found earlier;(the distributer and turn it till u find a point where the motor is at it's fastest idle. Retard the distributer just a little, ).

This is how I do it, and my car runs a lot better now. U don;t want your car retared so much that it sounds really good, and it wants to die. But not too advanced that it's where the point of breaking(the fine point discriped above.)


I hope I helped some what. I'ts hard to explain w/o doing it myself.

If this doesn't help your prob, plz repost.
