Engine Timing

[81_Chevy]

Well im still having some timing issues with my truck, but it runs for now.

ive searched the web and here for how to time my engine, there have been things here and there but nothing that really specifically tells me how to time it. i know the basics on how to time it and everything like how to adjust the distributor cap and use the timing light and everything.

one this i have seen is that your suppose to unplug the vacuum advance line that goes to the distributor? ive never done this in the past.

pretty much im asking for a semi detailed basic, 1. 2. 3. etc on how to time my engine, thanks in advance -Nic

If you know how to hook up the time light, then I won't go into that. Make sure you can see the timing tab on the front cover and the timing mark on the balancer.

Unplug the vacuum line from the distributor an plug it with a screw or something. If you leave it unplugged you will have a vacuum leak. Loosen the hold down bolt to the distributor so you can turn the distributor to advance or retard the timing. Start the motor, hopefully it is at operating temperature and the choke is off. Point the timing light at the timing tab and see where you are initially. Shoot for 10-12 degrees, and tighten down the distributor. Reconnect  the vacuum line to the distributor and you are basically done.

If you want to check total timing rev the motor to about 3000 rpm while pointing the timing light at the tab and record the number when the timing mark on the balancer stops moving. should be around 32-34 degrees.

 Start the motor, hopefully it is at operating temperature and the choke is off.

     These are two important points.  On the second, you want it at full operating temp with choke off before timing it.  Otherwise where you set your timing will be slightly off when it does get to full temp. ( which is where most of the time our vehicles run at ).

I'm just adding my two cents here; I keep several golf tees in my toolbox, because they work perfectly for plugging vacuum lines when I need to.
