Default Re: Unknown bikcycle engine part

What you have is a cns or a cns clone, the lever mounts on the handle bar and is the choke enrichment . The tube on the bottom of the bowl is the overflow in case the float needle gets stuck open, just let it hang down. The one closes to the air cleaner is the vent from the bowl so fuel flows freely into the carb, the other I don't have on my cns. what you can do is loop them over the carb and zip tie them so water can't get in. I hope this helps, Greg
Your results may not be the same,Greg
