I am a new rider and need a little advise. My sled runs great but every other time I ride it I have to change the plugs. I think it may be running to rich. Anyone have any ideas where a good starting point would be on adjusting my carbs? Maybe thats not the case. I just need help.

go check here http://www.snowmobileforum.com/engi...rk-plug-diagnosis-spark-plug-application.html on spark plug diagnostic, and compare the colour of your spark plug

I had one these and if I can remember correctly I had to jet down two sizes from factory before it would quit fouling plugs.
