I recently obtained a 85 ATC 200s. This trike has been sitting for years. I emptied and replaced the gas. Changed the oil and completely cleaned the carb out. Also removed throttle cable and confirmed the little c clip is in the middle groove on the needle. New plug and foam air filter. The trike starts right up! I put the choke on and it runs at full throttle. When the choke lever is pushed all the way down to the off position it absolutely screams. Adjusting the idle screw out and it does nothing. Can someone help? Could it be the throttle cable? I sprayed carb cleaner on carb and rubber hoses while idling and it doesnt make it rev worse. Doesnt appear to be a vaccuum leak. Please help.
