Do one side at a time..Take the cover off and replace the parts in the same order that they came out..Ther will probably be extra parts, as the kits fit more than one carb type...The cover with the screw in the center has the gasket next to it, with the thin blace neoprene or brown material against the carb body..On the other side the gasket goes against the carb with the diaphragm on top of the gasket, then the cover...The @#$%& little spring is easy to lose, do it on a table where you can see it when it jumps out of place...The lever hooks into the ring at the top of the inlet needle
Don't bend the lever..It should be flush with the casting next to it, not the top where the cover fits....
