Timing, rotar arm direction

[physicsfool]

Evening all,

So i am timing up the G. And the Haynes manual is saying that the rotor arm should be pointing to where you connect lead 1 up to the distributor cap.
However mine seems to be 180 degrees out. Instead its facing 4. taking the leads as (1,3,4,2).

I am taking position 1 to be the point closest to the front of the vehicle on the distributor cap.

how should one proceed?

l-3-4-2 (No 1 at timing belt end)

Ay, However when the dot on the pulley is matched up with the marker on the casing for the camshaft alignment the rotor arm isnt facing lead 1 its facing lead 4.

[Jezza-7]

Oh, thats odd.

And the crankshaft timing pointer is matched correctly as well?

[physicsfool]

From what I remember, when in the alignment for the camshaft I remember valves for pistons 2/3 being open. Does that sound right?

There is only one way to attach the camshaft right? It has a woodruff key. But I am no mechanic so happy to be proven wrong

Ensure timing marks on camshaft pulley and crankshaft pulley are both correctly aligned. Having just timing aligned will give you a 180 degrees off

OK, I lined up pistons 1 and 4 in TDC.and when looking at the trappets valves for the other 2 pistons are open.

The only issue i see is that a whole rotation on the camshaft pulley wont make a difference to the placement of the rotor arm.

PeteG40 thinks it could be a case of the dizzy simply being rotated 180 at the point it joins with the camshaft. i will drop it out this weekend and see if it has been tampered with on the back
