More special carburetor tools, in this case more on the lines of repair than tuning.
Beginning with number 1, the special Torx screwdriver is needed on many of the Mikuni carbs used on Suzukis.
Next (number "2") is a group of very special taps, in sizes and pitches to match the various threaded parts on Honda carburetors, such as for the pilot screw towers.
Item number "3" is a mini butane torch, commonly used to remove the super-glued mixture screw limiters prior to servicing the idle mixture circuit. I prefer the soldering gun method now but this was commonly used back in the day.
Number "4" is a tiny ball-tip Allen screwdriver. This tool comes in some jetting kits for the purpose of adjusting the jet needle.
The three tools in group "5" assist in the cleaning of the carburetor's passages, specifically the idle circuit. The first item is a piece of wire in a pin vise. The second is a needle tip for the air blower. The third is a shop-made mixture screw o-ring retrieval tool.
Number "6" is another tap, this one custom made from a broken enrichener valve.
Item number "7" is another tap. This one is designed to tap new holes in Honda fuel valves ("petcocks") so that they can be rebuilt.
The two tools in group "8" are custom fashioned to help extract broken mixture screws, a common problem in carburetors.
Number "9" depicts a factory Honda jet wire sizing/cleaning set. A very handy tool, this, unfortunately long discontinued and not to be confused with the acetylene torch cleaning files marketing as carb tools online. Stay away from that stuff!
The drills illustrated at number "10" are commonly sold as jet drills, though they are made for gas furnaces and not sized in increments very suitable for carburetors. While no substitute for the correct size jet, they are handly for jet cleaning and sizing. Real carburetor jet drills exist however, most notably by Weber. But the gas furnace ones offer more in-between sizes.
Finally, item number "11" is a Mityvac connected to a custom made fitting designed to test float valves for leakage. It is used for other purposes also.
