If it doesn't fire after 3 or 4 pulls it is time to think about the electrics.
There are 4 electrical devices on the engine. Coil - CDI Box - Stator - Trigger Coil & CDI Box are easy to change and most likely the problem - The trigger is located under the plastic cap on the recoil side of the engine and is easy to check. The Stator is located under the Flywheel and is relatively involved in replacing, unless you have the proper puller for the flywheel. If I had to lay odds on what is bad....2-1 it is the coil.

I'd like to bounce a situation off the list as I attempt to start my rebuilt 494 that I've bolted back into my KBS. The situation: -140 psi compression on both cylinders -spark at both plugs -40:1 premix in a spare tank that is getting pumped to the carbs -idle air mix screws set per the SkiDoo manual (seat screw and then back out 1.5 turns) I'm assuming proper timing on the rotary valve and the magneto firing. The engine has refused to fire after 300 pulls on the starter cord (it's a total body workout!). It feels like some combustion is helping on some of the pulls, but it's not firing or attempting to catch and run. Are there other things that I need to check or do? Thanks for any and all assistance, Kenneth Kirkland #18MiDiv / Arkansas Region(77) 1991 KBS Mk.
