Sorry, I'm from Sweden so I write in (not so good) English but I hope I'll get an answer.
Anyone who knows the original correct ignition timing for the FS-1?
I know it's not adjustable, but I'm building a modified ignition with CDI and I missed to check the original settings.
I'm now at 26 degree advanced and it works wery well, but I want to know what it was with the original ignition.
