Here's the choke on for starting. Notice the fuel line nipple and the little red gasket well this nipple is almost always loose when the kit is shipped so it will need gentle tightening. and on the tank there is a little red gasket between the tank and fuel valve. It is most likely laying loose in the kits box and most people won't have a clue as to what or where it goes. I also use the cheesy fuel line but add the stainless steel safety wire on the fuel line fittings as it works easy to use and doesn't cost much. Notice I bent the wires ends so you don't get a free tetanus shot when you touch that area.
