I've read most of the threads about ignitions and timing. A lot of people seem to possess timing lights. But there was nowhere to read how the timing advances or retards as a function of rpm.
Now I did it, and here are the results:
The woodruff key has a little bit play in my crankshaft. We should keep in mind that 0,1mm play corresponds to 1,4° change in the ignition timing. I fixed the piston and turned the magneto to the left. Then I screwed down the nut.
I mentioned that measurement is my third hobby.
Has anybody got other values? Has anybody got any values?
