Hi i have a 1982 kawasaki js440 the the motor turns off but it does not sit at an idle i have no idea whats wrong? what hsould i do to start it to keep it idling and is there any tests i can do and how can i do them? please help!!!!!! also i disconnected the hose where fuel is added because the gas cap had a crack in it and was letting water in. could this be my problem for it not being to idle?
