I wanna time my truck but don't know where it is. /forums/images/graemlins/crazy.gif
The vac advance is right on the distributor...look for the vacuum line. /forums/images/graemlins/smile.gif
I saw it on other trucks... It has a canaster sticking out of the passenger side, right? Mine doesn't have that.
Is your engine carburated or throttle body injection?
Do you know if this is the original distributor? A carburated engine should have a round diaphram housing on the side of the distributor. A throttle body engine doesn't have a vacuum advance. I'm unfamiliar with what was standard in '86.
I'm not sure if it's the original or not. /forums/images/graemlins/confused.gif
Hey wait, is yours an 86?
It could be that Stupid ESC, electronic spark control, if so you have to short 2 pins on the computer harness under your dash and then time it.
Talk to me on my Cell I will explain it better and I might even have a diagram for you from my haynes.
CA truck it's probably full CCC...no mechanical OR vacuum advance if so.
Yep, I have an 85K5 with the wonderfull cali. smog equip. /forums/images/graemlins/rolleyes.gif You have a CCC and the ESC distributer.
