there should be a adjusting idle screw on the bottom of the carb..if not..then it's on the side..it will have a spring on it..as for the c-clip..yes..center is stock..the reason they put 5 groves in them is..for when your jet needle wears the seat..or your needle jet wears..you can lower or raise it to allow better fuel mixture.

The clip should be on the 3rd groove from the top. This shows the air screw adjustment.

i can adjust the idle with the nob on top of the choke but it will idle with choke up but when i push choke in it wants to shut off unless in giving it gas i have it turned out 2 1/2 turns.
