its been real cold the last few days and my carbs are froze solid i cant open the throttle by hand on the carb. i put a heater in there and it loosens up but the next day is the same thing. should i oil it up maybe also im sure letting it idle would warm it up but it wont stay at an idle ive been playing around with the choke cables alot and thought i got it figured out few times but apparently not. i set the pilot air screws according to the manual so i know its not that. any info or opinions on any of this would be hugley appreciated.
