I don't know the engine year but the engine have the no tubes sparkplug,I think it's 76 and up,this engine has been change by the former owner,I have a point distributor since its in my 66 valiant
So all the verbiage about '76 emission controls and manuals and such does not apply. You've got an engine configured as in the '60s, with a '60s distributor.
Disconnect the vacuum advance hose at the distributor end. Stick a pencil in the end of the hose. Set the engine idle speed to about 700 rpm, and the basic timing to between 2-/12° and 5° BTDC. Reconnect the hose and readjust the idle speed as needed. All done.
