i just bought an 08 skidoo summit x 163 and i have fired it up a few times and it has started and ran fine.. just changing plugs and chaincase oil for the season and the plugs have brown oil on them and are wet.. i dont know if this thing was summerized when i got it and it has been started 3 times total since i bought it...thinking that that oil if it had been summerized should have burned out by now...my oil cable is currently at 18-19mm when measured, i think it is suppose to be at 16.5mm, would this make it run rich or lean??....any thoughts??
