Carburetors were ready for assembling, however I have a couple of other works to attend to, thus I placed parts of my Mikuni BS24 carburetors onto the shelves and smaller of them I put in caps from carburetor cleaner spray, grouped according to their destination. Those carburetor cleaner caps are mighty useful things when it comes to sorting small parts/hardware that one doesn’t wish to mess to.
After some thoughts I decided to grease throttle arm joints and throttle shaft bushings with Plastitube grease. It’s suitable for such kind of application and it withstands high temperatures as it’s designed to be used in brake systems.
Now let’s pack every carburetor body with pilot jet, needle jet, emulsion tube (air bleeding pipe), main jets and starter plungers. Mind, you have to install all starter plungers before assembling carburetors rack, as after starter plunger’ nut on second carburetor couldn’t be easily accessed with wrench or socket.
Be this carburetors assembly part of restoration project, I’d have no choice, but use original hardware. However, its custom project so I found no objection against using stainless steel hardware with hexagonal sockets, including those screws with countersunk heads for carburetors to heat shield mounting.
After rack is assembled, we could put into carburetors throttle assemblies and install throttle shaft and then choke actuator.
Yet one usage for caps from carburetor cleaner rattle cans: rack of carburetors might be installed upside down on two of them. thus installation of last components became easy game. Valve seats and valve needles on their place, as well as small O-ring for accelerating pump jets.
I also head a small issue with Keyster float bowl gaskets. The hole for the pilot screw shaft (in fact for shaft where pilot screw has to be, as only early models of VM24 carburetors has it there) turned out to be a little smaller than original one. Keyster gaskets are made not of paper, but of two layers of rubber with reinforcing layer of fabric between them, see photos below:
