    difficulty setting ignition timing on my 4g64

    Hey guys first post here. Just bought a 92 mighty max with a blown head gasket for my work truck. Anyways rebuilt her from the head up, she runs pretty Damn well. Anyways ive never had to deal with a dizzy before and just a tad confused here. I have a dial back timing light to get the timing. Ive attempted timng it multiple times. She runs and drives fairly well. Just in lower RPMs it shakes a little more than id like. Anyways is there maybe.DIY on setting ignition timing or what do ou guys set yours at? All ive seen is 5 BTDC and 8 BTDC and i beleive ive tried both. Still doesn't feel right.Any help would be awesome

    since you changed the timing belts recently, did you follow the thread on the correct way to install the timing belt? The book method will put you one tooth off. The other cause of roughness is the silent shaft being 1 tooth off.

    Well the first time i put the timing belt on i fogot to make sure that the balancer on the main timing belt was i guess you would say "balanced", like how you're supposed to spin it until its balanced on the mark, idk i watched a video, anyways i took both belts back off and lined up the marks after spinning both balancers to balance them. Put everything back on. It idles smoothly although the truck doesnt have a tachometer. It will only shake for a couple thousands rpms and its smooth the rest of the way out. Just a little shaky when i give it initial throttle. All the marks line up though. If it wereoff a tooth wouldn't a mark be off?

    Also, when setting the Timing you need to put the ECU into "timing mode" to set the base timing.
