Please help!! 1971 340 duster having major ignition wiring headaches.

Poping back through the carb, good chance the loose timing chain jumped a tooth or 2.

Easy test, set the distributor cap off to the side so you can see the distributor rotor.

Then get a socket on the front crank pulley bolt head with a breaker bar and rock it back and forth to see if there is excessive delay before the distributor rotor moves.

A little delay is OK, a lot of delay is not.
