    Ok, new thread, my timings out by 180. Really after some confirmation or being told 'what the fuck you on about'.

    OK the piston makes two passes of the bore per cycle. Down 1 (suck) Up 1 (squeeze), down 2 (bang) and up 2 (blow). It should spark between up 1 and down 2, but it's sparking between up 2 and down 1. Obviously, it's the timing when it sparks which is wrong.

    So I'm working out how to correct this, does it need one rotation of the crank so the piston goes up and down once so it's back on track timing wise for the spark? Then the timing belt putting back on?

    If it is this, then I'll need to remove the cams so all the valve are shut? Rotate once on the crank back to TDC.

    Sorry if I'm compley wrong or there's a better/simpler way to do things. Any advice is greasy appreciated.

    Why did you not just lock the flywheel?

    Have you kept standard cams or changed them? Think cam means did you lock the flywheel at tdc when you did the timing?

    If that's what he means, then yes I did. But when I put new rings in I cranked it a few times by hand then stuck an Allen key in to lock at what I'm thinking now may or may not have been TDC.

    As I mentioned in my first post I think I locked it incorrectly as in no1 was only half way through the cycle why I think it's causing the timing to be 180 out.

    just turn the crank back 90 degrees so all the pistons are half way down the bores then turn the cams 180 then turn the crank back to tdc and retime

    Good in theory as this was my first thought, but I can't lock the cams when turned 180 degrees. Why I need to rotate the crank half a cycle I think.
