Re: Love the motor bicycle
If you can't find a clamp small enough you might try a nylon tie-wrap or just a twisted piece of small gage wire around the tubing and nipple to snug it up a bit. 3/16" I.D tubing works well on most carburetors. Look for fuel line in the lawnmower section of auto parts stores or home improvement, hardware stores for a better quality fuel line that comes in the kits. Ace Hardware and O'Riley's carries lawnmower parts as well as motorcycle shops and small engine repair places.
