Nothing really. Like I said I think its a tooth out on the timing. But I never changed anything to get it to run, it still takes forever to get it to start. Now that I have had it running though I know where to go from here.
For future reference to anyone else wanting to do a timing belt, the most fool proof way of changing the belt if the timing marks aren't spot on is as follows:
Before removing the belt use some kind of marker (e.g. tipex) that will mark both the timing belt and the pulleys. Use it to mark three teeth of both top and bottom pulleys and mark the timing belt in the exact same places. Then when you take the belt off you can transfer the marks from the old belt onto the new belt, making sure that the spacings are exact by counting the teeth on the belt. Then all you have to do is line up the markings on the new belt with the marks that you made on the pulleys earlier. It will should almost definitely be timed the way it was before with this method.
Note: Make sure you check/note the direction of rotation of both belts as you do this!
Sorry If the instructions are confusing and this is not guaranteed and I cannot be responsible for any problems. I have enough of my own!
This method works for any car and is how I was taught on my last first time successful timing belt change. I decided this car was too easy to bother, big mistake!

But I have learned my lesson.
