Inline Six Timing
I am new to this so I appreciate any help I can get.
91 f150 w/ 4.9L inline six
I replaced my distributor today and am unsure how to do the timing.
First thing is how do you get the damn spout connector off? Is there a special tool or something.
Second, the hood says to adjust the timing with the engine running, is this possible?
I am sure I will have more questions later.
Again any help is appreciated.

Don't mean to hijack the post, but this is related.
The 300-6 EFI I am working on has 2 sets of timing marks. One set is cast into the timing gear cover and the other is a bolted on timing tab on the right hand side of the engine. Which do I use? Why are there 2 sets?
Thanks,
DannyP

You use the stamped steel on the right. Don't know why there are two sets of marks; maybe the others were used on carb engines or 240's?
The spout connectors should just pull out of its recepticle. If it's never been out before it will probably be hard to get out. The engine must be running to set the timing. My truck likes 14-16 degrees.

When finding the mark on the harmonic balancer, make sure you use the fine line that goes all the way across it. It may be hard to find. Do not use the V notch. Drove me nuts until I figured that one out.

My advice -- forget the timing light. Turn your motor to #1 cylinder top dead center, now turn your distrinutor to fire on the #1 cylinder. Pit the cap on, leave the dustributor loose, crank the motor, rotate the distributor until the motor sound smooth. Works like a charm. USe the light and the marks are hard to even see and when it says it correct, even advanced a little, my motor wasn't running all that well.

Spout did come off with a little muscle.
Got the timing adjusted seems OK. Only thing is after about a minute of running the timing starts to jump around a little (a couple of degrees up usually). Happened with and w/o the spout in. Is this a serious problem?
Thanks for all your help.
