my carb has been actin up it will not idle unless you set the chock. when it idles with out the chock it back fires and you hear a knockin sound on the inside when it tries to idle then stalls out .had some bad gas but put new gas in with seafome. runs good at speed just not at idle clean carb about 4 to 5 times. clean out fule tank and installed 2nd fule filter still dooing the same thing as before dont know what to do know help????????

 

take it to the stealership for them to look into your problem. i have no idea why it would be still doing it unless there was something in the carb jets.
