Default Distributor question????

Hi guys i noticed today after reading the manual a little that my rotor is not perfectly lined up with that notch in the distributor housing. The manual sais to turn the rotor to line it up, i am at TDZ according to the mark on the belt pully. I put a little pressure on the rotor but it doesnt want to turn and i dont want to force it. Is this a big deal or does it need to line up perfectly?? If so how do i turn the rotor???

Simply looks like your static timing is off by about a couple of degrees or so. Did you set your timing by the book at 4000rpm? Changed your timing for altitude, octane, modifications?

There's a thread on Pelican about ignitions and someone mentioned the dizzy can be off by as much as 5*. I woudn't be surprised if this is the issue here.

Once you get it running, check it with a advanced timing light.

I've never seen one on a Porsche or BMW line up absolutely perfect to that notch while the #1 cylinder is at TDC.
The width of the electrode on the end of the rotor is there so the current is not going to jump sideways to get to the distributor electrode.

I would not worry about it.

Jerry,
If you read the top of the page of the manual, it states it is a "basic adjustment of distributor". This will get you in the ballpark when setting the initial (static) timing if the engine has been worked on, i.e. engine rebuild, distributor R&R. Of course, you first have to make sure the cylinder #1 is at TDC WITH intake and exhaust valves at rest. With that basic setting you should be able to get the engine to fire and then set your timing properly with a timing light.
