I had a very similar situation last season when I rebuilt my 494. No matter what I did it would not fire. I went through the process retracing my steps of everything I did during the rebuild and the only I could think of was that I changed the trigger switch (probably not the right term) or whatever the little thing is that is on top of the magneto. Anyway, I had gapped the pole to the specs in the manual but I thought since I am new to this perhaps I did it wrong. I took it back out, put it back in and reset the gap to the same setting and bam, she fired right up. I don't what I had done wrong but clearly I had done something wrong.

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.
