How do you adjust the timing on an 83 f150 300 i6

 

The first thing you do is check the timing. Then if it is off, then you can adjust. To check the timing, a common method is to use a timing light. This instrument fires a pulse of light every time the #1 spark plug fires, and this pulsed light is aimed at the timing marks on the engine to allow determination of whether of not the timing is correct.

The ways of adjusting timing depend upon what kind of ignition control system your truck uses. You have an '83 300-I6. Does it have a stock electronic ignition system?

 

I believe it is a dura spark the timing is off the distributor bolt was loose. Had to move distributor to get truck to start

 

I'm pretty sure it is the stock

 

Ok, well the duraspark II system is quite friendly to timing adjustment. Find your timing scale, it should be over on the passenger side of the crankshaft pulley, it looks like this.



Once you have found that, and cleaned it with a rag and solvent, you are ready to go. Found it?

 

Found it do I have to unplug anything

 

Yeah, if you have the duraspark ignition you "unplug" the vacuum line that goes to the distributor. Pull it off, and plug the line with something (a golf tee works well). Then check timing with timing light, engine running.

 

Thank you I'll try that soon
