Weird Distributor Behaviour

I've had a few issues with the Rover starting for a while now and decided to renew pretty much all the ignition side of things as the old electronic ignition was giving me intermittent spark etc. (I couldn't revert back to points as the base plate in the dizzy had been swapped out for the electronic ignition one)

So, I've replaced the distributor with a new electronic one, set the engine to TDC before removing the old one, fitted the new one with the dizzy pointing to the number one plug on the cap, however after I've tried to turn it over and when I realign the crank pull back to TDC, the distributor is now pointing to cylinder 6 spark lead, am I just being dumb and that it actually takes two revolutions of the crank to do a cycle?

...and I assume I really want to be aligning to 6 degrees BTDC and not just to TDC and lastly, on the pointer where do I align to, left, centre or right, I couldn't really make it out in the manual...

The left hand side of the pointer is where you time to. It should be at 90 deg to the engine, not at an angle. It is possible after all these years it is not in the right place anyway.
You can set it up to TDC by using a piston stop in a plug hole, rotate crank one way until it stops, note position on crank pulley, rotate the other way until it stops, note position on crank pulley. Halfway between each position is true TDC, straighten pointer and set to this position. Mark left hand edge with white paint for strobe.
When engine is running, remove and plug vac adv tube from dist. add extra timing marks to pulley to read up to 35 deg.
Run engine at 3500 rpm, set timing to 34 deg adv. Re connect vac pipe to dist, road test, if pinking occurs under load reduce adv a little.
Check what timing is at idle, but it is all in advance at 3500 which is important.

Great, thanks, I thought it likely the left hand side. I'll work through your suggestions, appreciate the help.
