Running rough after rebuild

[911 Rod]

Thanks for this help Bob.

Above you say "Pull dist and shift the ROTOR one or two notches to the right. That would be the gear at the base of the dist. CCW."

Right or counter clock wise?

Here is a pic of a 3.2. It appears to be a CW rotation vs CCW like my SC.

The position of your rotor appears pointing slightly towards the center of the of the engine, instead of slightly to the rear of the car.

Plus your rotor should be almost dead nuts in the center of that line at TDC. That is more than 3 degrees.

I say one tooth CW (to the right)

[Bob Kontak]

Here is the SC location of #1. My black mark looks a little too far to the right.

[911 Rod]

When I rotate CW 1 tooth it goes past the notch. Where it was before when you loaded up the rotor it is dead nuts to the notch.

The 3.2 isn't adjustable.

[911 Rod]

One tooth. The angle of the shot makes it look almost on but it's way off.

Thank God you have the ability to do this.

I eat crow and my hat for leading you astray and I see where it cannot be moved.

Why 47 degrees Before tdc, though.

I won't ever "advise on a 3.2 again". My hit rate sucks. I apologize.

[911 Rod]

All good Bob. Lol
You did have me running out to the garage.
So this leaves the flywheel sensor. Is it possible to install a flywheel wrong?

[Bob Kontak]

Ferrino - thank you.

One more thought. I am so going to deservedly get beat up.

Twist the rotor CCW. How much does it move.

Check your wires.

Are you running the stock chip with all those mods? Seems like that could cause some problems.

Rotor doesn't move at all CCW. It loads up the cams (or whatever they are called) inside the dizzy when you turn it CW.

You can't mix up the wires as they only go on one way. But ya, I checked it like 10 times.
Wouldn't it be backfiring if the wires were wrong?

It's a stock chip with some mods.

The problem is the timing. Does a chip effect timing? Everything I see the timing is set mechanically.

[911 Rod]

The culprit?

I have to think the movement on my 81 is from the vacuum advance and retard mechanism in my 81. Does not appear to be the case on your distributor because you don't have a pod (correct?) Mine moves maybe 1/2" at the tip of the rotor.

I don't understand the time sert location.

Note no advice. Just interested.

84 and up have DME (Digital motor Elecrtonics) and there isn't any adjustment at the dizzy. The DME fine tunes the timing using a reference sensor on the flywheel.
The pictures I have shown above is the pin on the flywheel that the sensor picks up.
Somehow it is damaged. I'm wondering if I didn't install my flywheel correctly and it has become damaged.
We have pretty much come to the conclusion that the dizzy is in correct.

The sensor smacked the pin, take a look at the sensor, if damaged, you will need to replace both.

Buddy up north just went thru this.

[911 Rod]

Draco. Can I ask what his symptoms were?

I was thinking that the sensor hit the pin as well until I found this before photo. The pin in the new to me, used, flywheel was already damaged.
You can never take too many pictures.

Normally, that pin is an allen head bolt. Yours looks like a set screw, not that it would make any difference if the height is the same.
