This is dealing with the VB22J carbs in particular but most of it applies to the VB21 and VB24 carbs. As everyone knows that has done these they are problematic to get right the first time at best so hopefully this will help you get there. In this case I'm dealing with VB22J carbs that have had previous attempts to rebuild and get right to no avail.
Tools/equipment needed: 7mm wrench for the jet holder, 8mm wrench for the left carb linkage and the sync screw locknut, impact driver to remove the screws with a #2 and #3 Philips tip, variety of screwdrivers that need to be filed and modified to fit, Allen wrenches that fit the new Allen screws you need to buy to replace every screw, 400, 600, 800 grit sandpaper, spray carb cleaner, jet gauge(optional), number drills #60 thru #80 available at RC car shops and some misc. stuff you already have laying around.
Stainless Steel Allen Head Screws: 8: 4x12mm, 8: 4x16mm, 4: 5x12mm, 5: 5x16mm, 4: 6x14mm
Carb Kits: I recommend getting the Honda OEM kit since it has the correct and latest materials as well as a couple of parts not supplied by the aftermarket. They do not include jets, float needles or air cut valves. Aftermarket kits include jets which unless damaged never need replacement and are for the most part the wrong sizes. Use those jets at your own risk knowing that you will likely be putting the originals back in.
Float Valves/Needles: For the VB22 carbs I strongly suggest the Honda OEM ones since they are the correct length. VB21 and early VB24 carbs with Black floats can use aftermarket float needles.
Aftermarket kits include float valves that may not be correct and the jets that never wear or need replacement.
