best way to time it ..leave the vacuum lines - O N ! - - thats the way its gonna run anyways , set it a 5 degrees at idle . . .then throttle up ..it will move to 12 degrees with throttle applied . . . .thats how it is supposed to run real time . .so leave the vacuum lines on !

We must understand ALL of the components in a system. You have static timing without the vacuum line, 0 degrees for 22r (carb) and 5 degrees for 22re (ECU). Vacuum advance timing, 12 degrees for both 22r and 22re, and then we have mechanical advance when the centrifugal forces sling the distributor weights out at high rpm. That, and an increase in vacuum, is why the timing mark "moves" as you rev the engine. The static timing is first then the vacuum advance helps during low to mid range rpm as the distributor's mechanical advance slowly takes over for mid to high range rpm. The combination of all 3 should gives us Total timing. You must set them all correctly. Too low of timing causes the motor to run too hot and sluggish with bad gas mileage. Follow the service manual.

I wish I could explain more/better but I'm down with a shoulder and typing off handed.

for the 22r,the 0 is for when u r sticking your distributor in,pulley on 0 rotir pointing at #1 spark on the cap...warm the engine ,remove the 2 vac lines n plug them, with hoses removed removed set your timing ti 5 degrees before top dead center,when u re attach ur vac lines it should b at about 12 degrees.
