If you have a manual that has the total advance spec you could set it that
way too. I actually prefer the total advance setting because that is wht
you are really after.

Terry-

I have been looking high and low for info on this jumper.

Would you mind taking an ohm meter and find out which jumper goes where so
I can make one? I would really appreciate it.

thanks
