What kind of ohm meter is needed to check the timing for when the point open. I have a fluke and i cant seem to find when the points open, my meter keeps toning at me and doesn't stop. I can see the read out go from 1 to 2 on the display but thats it. How far should the magneto move from idle to wot? Any ideas would be appreciated greatly. The max advance screw was loose when i got this and i cant get it to go over 2500 rpm at wot. I have a book and dial indicator but just cant see the points open on my meter.
