5yr old Homelite string trimmer. Has a Zama carb. Adjustment thingys are
not what I've seen in the past. I'm no small engine fixer type.

I had always seen two screws on springs in the past. This has two plastic
things. White one has a slot. Playing with it it appears to be the idle
adjust. Assume red one is for main but no slot for adjustment and the
little wing things appear to lock the position. Any hints?
