It goes together like Goober's photo shows with the washer against the spring, then the o-ring goes on last against the washer, then the entire stack screws into the bottom of the carb body until very lightly seated... then back it out 1 3/4 turns for initial adjustment. Follow procedure in the manual for final adjustment on the running motor.
That washer protects the tiny o-ring from getting cut by the end of the spring. As Goober said, you'll be sorry if you don't put that last o-ring back in there... if you don't have one buy another china kit from another china company.
