Ski won't fire

[brapjp]

Ok I changed jetting on my carbs went to fire it up it started ran had lots of power then seconds later it died completly and wouldn't restart. Now it won't start worth a damn just cycles over and over. Has comp has fuel has spark I even tried gas in the plug holes still not even a bump... Any ideas?

This is my ski guys I don't kno what it could be lol it ran fine before I changed jets just too lean. I put a primer kit in the return line only thing I changed carbs are getting fuel and coming out return line lol so lost

Could be a ton of things. If you're saying you have spark, have fuel, and have good compression...My next guess would be to see how strong the spark is. If it looks weak, trim the spark plug wires back as the wires could be corroded. If that doesn't work or the spark is strong, the flywheel and/or the stator plate could be loose. The spark has to be consistent and it has to be somewhere close to when it's supposed to fire.

The spark is a strong white blue it ran fine before that's what confuses me and I pulled flywheel cover and the bolt is tight .... How can u have spark in the cylinder with gas and it not ignite

That's what's got me figuring there is more to this. You'll need to pull the flywheel to really see what's up. The bolt may be tight but if the bolt isn't as tight as it's supposed to be, the woodruff key could've sheared and when you nailed the throttle the flywheel spun around the crankshaftcausing it to die as was described and the engine would not be able to continue running in the altered timing configuration.

Figured it out sheerd flywheel key lucky no damage all good now thank u sir for your advice
