I cannot find my Haynes manual, so i'm using my FSM to do this.
I am having an odd timing issue. I'm going to describe it the best that i can.
89 NA2T - stock block/everything
84T ECU
I begin with setting my crank/cams to TDC on #1. L3 & R3 are pointing to their indentations on the sheild, and the crank pully is on the 1st notch, 0 degrees:
I pull the disributor out and set it like this:
However, to set the rotor to the TDC position, i have to turn the distributor ALL the way to the right. (Red indicates the "center" position) The dist is now at TDC, but has no room to adjust both ways. It's like a max of 20 degrees, and all i can do is retard.
If i pull the distributor back out, reset the gear as before, but twist the whole assembly one tooth, i am in the same position, but opposite:
The distributor is cocked to the extreme left, now. The dist is now at TDC, but again, has no room to adjust both ways. It's like a minimum of 20 degrees, and all i can do is advance.
So, basically it's like i can't get it to be TDC on the rotor, and have room to adjust + & -. My situation is either one or the other, there is no middle ground.
Now i find this odd. I put the crank to teh 20 :
Odly enough, the distributor moves from far right (or left, can't remember) and it's in the middle of the adjustment points:
So now, with the crank at 20 degrees, the cam moved from one of the two extremes (right or left for TDC) to a center TDC.
---------------
When running, using my timing light i then have to turn it back to the left or right to recieve a 20 degree (or close, sometimes i get 25 or 15 degrees...it's just never right dead on at 20.)
I just got done fiddling with it, i left it at 25~30 degrees of timine. It ran horrible. It almost dies if i rev the engine, pretty much undrivable. On previous attempts i drove it at heavily retarded timing, and it had 0 torque until 3k or boost. The reason i'm messing with this is i had a problem with detonation (see previous post) and i momentarily fixed this by getting a timing light and finding out i was running 30-40 degrees of timing. I was never truly able to get it close to 20 degrees. I'm usually 5 degrees under or above - either way it runs like crap.
I looked into possibly my cam jumping a tooth but both line up properly when the crank is positioned to the 1st notch, 0 degrees. So i am out of ideas.
