    timing

    light or volt meter moves when the piston reaches .350" before tdc in direction of rotation. you gotta count needle revolutions and always back rotate past so you are approching the trigger in the direction of running rotation.

    The Hall Effect sensor trigger must happen way before 25 TDC. The CDI is a timing retard unit. By triggering it at 40 degrees before TDC the CDI is always taking away timing. No way a CDI unit can fire before its triggered.

    Im not really following you. What do u mean by needle revolutions and the numbers 25 and 40?

    dial indicator

    as you rotate the crank back and forth from tdc to btdc its easy to actually go a full revolution on the dial, 25 degrees or 40 degrees.

    but you have to go past 40 degrees BTDC to reset the trigger sensor every time so as to trip it properly in the direction of running rotation.

    timing

    i've also got a chopped stator cover,uses 2 bolts to hold just a small part over the bendix to keep it in place,that way you can access right to the allen bolts to time it if need be with out taking the cover off and on back and forth,just trickle some oil down the carb throats an run it long enough to see it

    Were is the Documentation that states .350 is the number for static timing (the magic #) for the 1200. I haven't found it in the service manual searching yet.

    timing

    The Polaris service manual doesn't list any # for static timing at all, the same # came up on three skis I checked non-fuel injected 1200's.

    the Polaris cdi is strictly a retard unit. if the trigger happens at 23 btdc how can it fire at 35 btdc???

    .350 is like 42 degrees btdc and everthing gets retarded from there

    Thanks,I understand what your saying,but somewhere there should be something on some Documentation somewhere. Just would be nice to add to my referances.

    I need to time a 1200 also, and would much rather do so when it's on the bench!

    The '99+ hull looks like it's gonna suck to adjust if I have to keep adjusting the flywheel in the hull!

    I know SLP www.startinglineperformance.com has the "timing kit" dial indicator and sparkplug adapter for around $50
