Ive a zx636 b1h and the choke on the left hand bar wont budge an inch, is it a choke and is it supposed to move to aid when i start in cold weather

Little black knob on the front left side, partially out is warmer weather cold start, all the way out is cold weather start.

1st add fuel/oil mix to fuel tank , then top off oil tank with bar oil , place saw down on flat surface , press 'ON" button above trigger handle to ON (its marked on case) then pull out blue choke handle till it clicks and stays out , press primer bulb with thumb 8 to 10 times bulb will become harder to press as it fills carb , push chain brake forward (on) ` place left hand on top of saw and right hand on start cord , hold saw down firmly and pull cord vigorsly several times till it sort of starts (sound) , squeeze trigger in and pull cord once more , saw should take off running , chain wont move ,walk to wood pile then disengage the chain brake and cut wood , if saw fails to start after this procedure then there must be a fault in saw , consult a exp small engine dealer for repairs

Mine does the same thing. I put a new gel battery with high cold cranking amps from Advanced Auto Parts. Look to spend 100 bucks. Choke at full choke and it starts right up now. Gold Wings are cold natured. I own 2 and both are. But the battery took care of the cold starts.

Without much other information of what has been done, I would start with the choke system. The choke cable may be detached or far out of adjustment. With a helper see if you can watch the choke cable move the choke lever on the carbs when you move the choke lever to full choke. Cables do break and or stretch. If that is the case then reconnect, replace, or adjust as necessary. If the choke lever and carb choke system is moving correctly then the problem may be in the carburators themselves.

Good Luck

That isn't a washer, its a "c" clip, use a flat blade screwdriver and pop it off then slide the pin out.

Coolant and intake air sensors adjust fuel like older cars had chokes to aid cold starts. More than likelt the coolant temp sensor

Are you saying your motorcycle will not run unless the engine is NOT CHOKED?

That is how it is suppose to run. Choke only when needed in cold weather.

Perhaps I misunderstand your question?

To start up a cold engine requires reach mixture (air-gas).In your case it seems like the choke is not working ,so cold engine cannot start.If it is an injection operated system then it must have a temperature sensor which suppose to turn the choking on when cold engine needs to get started.Either the sensor is faulty or the choke or between the two there is a faulty connection somewhere.
