Timing chain.


...........and why actual troubleshooting is SO MUCH more important (and cheaper) than throwing parts at it.

1....You check (ed?) if there is spark and fuel
2....You did a compression/ leak down check?
3....AND THEN CHECK THE IGNITION TIMING before you turn a wrench on the points/ reluctor/ distributor "anything." That right there will show you if the timing chain jumped.

"Other simple stuff". Pull cap, watch rotor. Wrench engine back and forth, "feeling for slack in timing chain, watching rotor. Determine what these points are, and then look at the timing marks and see how far it moves "with the slack." "A few degrees." More than 5? getting pretty loose!!!!!
