Yeah its gonna be hard finding out what type. It dont have that black cap on the top by the throttle cable. I'll try and get some pictures of it. each carb has one screw/spring adjustment. one black choke. two tubes one coming from the gas and entering the bowl, one exiting the bowl and going up to the top of the carb were the air induction is into a valve with two conectors, one is caped off with a rubber piece . pretty tight.they all tubes look like nothings flowing through them even when the bike is running. I was successfully able to start the bike idling it with chokes down while opening the throttle for about 2 mintues then it shut off.
