Also-How do you turn the heat on? The knob on the firewall says 'r heater'
That is like your choke cable. It goes to the valve assy heater control. Host has new ones. It is under you intake manifold. My ones are push in to be on. IE Water gets to the heater block. The fan switch is on the dash panel. Up should be off. Two speed fan
Due you still have the orginal Air Silencer (air filter) Looks like a muffler.
