The wrench I posted is for holding electric clutches while torquing the bolt. Most Warners have a very heavy insert that is round with 2 flat spots but its recessed up so you cant get to the flats easy.
Also for the Honda carbs, honda has a nice Jet cleaning set with 10 sizes of wire that isnt very expensive. Probably have 3-5 of them around the shop right now. Look like torch tip cleaners but they are just smooth wires.
