I'm putting a spool control cap on a C3 that came used without one.  Parts pics added.

 

Should the lock spring be added to the spool control shaft with the "wings" facing out (i.e. toward the cap) or in (toward the spool)?

 

(I think it does, since there are tiny indentations in the spool control shaft).

 

Also does the little square copper shim just sit between the cap and the lock spring?

 

Thank you!

 

 

Just leave that little plastic piece out. The reel will work just fine without it.

Copper piece in the cap first, then plastic piece, so the flat part sits against the copper. The little clip bits catch on the groove in the axle as you suggested. The reel will work fine without it though, as suggested above.

Thanks guys; also, is there a way to "feel" for the tension to see if the knob etc. are working Ok before putting line on?

Disengage the gears (press the button of the cast bar, depending on model) put your thumb on the spool and wiggle it side to side. You will feel the spool move and gradually decrease the amount of side to side play as you tighten the knob. Set it so it just stops having any side to side movement, put some line on it and give it a cast.

@Tim Kelly thanks, I'm in business now.
