.Not such a stupid question it is not really mentioned on too many forums for the first gen.
Do you have a service manual? They are free on the internet. EC.PDF is the one you need to read.
I will give a break down
Run engine for 2 minutes at 2000 RPMs
Then rev engine 2 to 3 times to 2000 - 3000 RPMs
Turn off engine, unplug throttle sensor
Then turn truck on rev 2 to 3 times to 2000 - 3000 RPMS
Hook up timing light to check timing.
To change timing keep engine running after hooking up timming light
Loosen do not undo the distributor hold down bolt (12MM I think).
Then turn distributor a bit and then check timing.
You can advance it or de-advance it by turning the distributor.
10 degrees is stock setting.
After setting timing tighten bolt, turn off engine, plug the sensor back in. Take for test drive.
