Slight misfire after timing belt replacement?

[tonyt102]

Thanks very much for that, I think I now understand the reason for a tapered cam sprocked as opposed to a keyed one. I'm guessing that the cams can be completely locked in place along with the crank (?) then, the belt could be removed, refitted and tensioned without any of the engine moving. This means that no Tip-Ex marks are necessary. Does this sound right?

Like you say, I need to get the cover off to check if they've marked the sprocket and engine. I'll do it tomorrow and report back.

Thanks again.
