If you've run outta adjustment you are probably one tooth out
Turn the engine to TDC # 1 cyl.
With the dissy cap removed note where the rotor is pointing (suggest taking a pic). Carefully remove the dissy without turning it, as you pull out the dissy, the rotor will turn as it has a helical cut gear.
Once the dissy drive gear is disengaged do not allow it to turn within the dissy. Take note of where its pointing now that its disengaged from the drive.
Assuming that you have managed to do this without any unnecessary rotation, put the dissy back in but with the whole dissy at @ 10 degrees (in the desired direction) from where you started.
This is a quick way of doing it, but not always easy to manage. If you cock it up then you start again,useing the procedure in the workshop manual.
