Sure enough the wifes quad tried to start but died. Changed the plug, nothing, checked spark, good. Ok I guess I got sometime pluged in the carb after changing the pilot jet. Take it off, for kicks and grins, I turn the motor over to look at the piston skirt. Call it habit from 500 ownership. There's no reed valve on this motor. Crank it a little more and shes running.
Lastnight there was a small pool of carb cleaner at the piston skirt so I guess it finally seeped passed and was laying on the bottom. Put the carb on, runs great.
I just had to get this one out.
