It`s no way of advancing the timing as the coil is fixed.
The only adjustment i was able to do, was to minimize the distance between the coil and the flywheel,
in order to create the strongest spark possible. The smaler the gap, the stronger the spark!
I did that by losning the bolts holding the coil and then put a piece of paper between the coil and flywheel and then
fastening the bolts again. Then remove the paper and rotate the flywheel in order to check that it run freely.
As my flywheel was not 100% round i had to do this a couple of times.
I`m gonna make a custom bracket to hold the coil that makes me able to adjust the timing.
I just didn`t have the time at this moment. I read somewhere that the optimal timing was 26 degree`s.
I don`t know what the original timing is, but from what i understand it will mayby give me 1-2 HP more.
Also here are som more pictures of where this "plastic manifold" sits on the engine!
