Adjustable Jet kit - Mikuni TM24-9

Instruction Note! The small brass tube, circled in picture 2, is cut 6 mm. Move the drain hose from your old carburetor and connect to the corresponding nipple. Thread the hose through the float housing loop so that it points upwards (figure 3). This hose serves two functions 1) indicates current fuel level 2) prepares for possible power jet connection. Set the adjusting screw to 2 turns out. This corresponds approximately to a 350 nozzle. With that setting the engine will probably run too rich. Stop and turn the screw in 20 degrees between each test rep. Repeat the procedure until you notice that the engine comes to life. To make sure you haven't screwed it in too far, open it slightly again and repeat the test. The correct setting is just where the motor no longer runs for grease. I.e. the same principle as when you test for the right fixed head nozzle. The adjustable nozzle has a flow range corresponding to mikuni hex (4/042) size #0 to #350. Approximate values below: 1/4 = #60 1/2 = #110 3/4 = #140 1 = #170 1 1/4 = #210 1 1/2 = #250 1 3/4 = #300 2 = #350 Leave the transparent vibration cover on. It is still perfectly possible to use the adjusting screw anyway.
