Hello,<br />I have a 2001 F50TRLZ yamaha and the choke does not work. Part number of engine is 62Y L 422***. I need to know how to test the parts on the carburetors, these are two solenoid looking devices. Also I need to know how to test the wiring harness. The switch on the key has tested good with a continuity meter. Is there a control module somewhere on the motor for the choke?<br /><br />
