In my tune up book it reads:
1965-1969 SPL311(1600 engine)
Spark Plugs NGK BP-6E Gap .28 -.32
Distributor Point Dwell Degree 49-55
Point Gap Inches .018 - .022
Basic Ignition Timing Degrees 16BTDC @ 600 RPM
Compression Pressure (PSI) @ 350 RPM 181 PSI
Valve Clearance Intake & Exhaust .017 Cold
Idle Speed 600 RPM
Firing Order 1 3 4 2
#1 Cylinder is the front, #2 is next, #3 is next, and #4 is last.
Distributor turns Counter Clockwise
As you put your finger over each hole in the firing order, 1 3 4 2. you
will feel air come out of the Spark Plug hole. That means the valves are
both closed. Adjust them now, in this position. Rocker arms up off the
Valves. When the valves are open, allowing movement of Air and Gas in/out
of the chamber, the rocker, or Cam is pushing down on the valve compressing
the spring. The spring moves the Valve to the Closed Position so it forms
an airtight seal in the Cylinder.
