2000 mm 700 questions

[putzy]

Hi, i have a 2000 mm 700, at at idle the sled doesnt seem to fire on all 3 cylinders correctly, middle cylinder and mag side cylinder will heat up upon starting but pto side stays cooler, sled runs great anything over 1/4 throttle, compression and spark seem to be okay, had carbs off cleaned out pilot jets etc,, .could i have a slightly scored piston, or air leak on engine, are the stators known to have issues? Thanks for any info

You can put a multimeter on the stator and pickup to see if it is within spec. I would double check the carbs it sounds like a fuel issue. You can try to put a spark plug tester in and see if it stops sparking on that plug at any point.

Move coil. See if problem follows.

Or, Swap plug caps and see if problem follows.

Remove the plug cap from the wire and check resistance. Should be 5K ohms.
