[BRUCE ROE]

Any car that old needs the timing chain changed, did you? Regardless of miles, the sprocket has plastic teeth that can wear or crack & fall off at any time.

You can check the chain by removing the distributor cap and rocking the crank by hand. If you move the crank 6 degrees before the rotor starts to move, the chain is shot. More is impending disaster. A roller chain replacement is best. Bruce Roe
