It is not really a very tight interference fit. Hope you like oriental food, cuz your gonna need a chopstick! First remove everything in the float bowl, most importantly the main jet (26) and emulsion tube (25). Next unscrew the top and remove the whole slide assembly. Now take your chopstick through the open top and push your needle jet (24) out through the float bowl. Probably gonna be fairly stuck if you have never removed it so only use as much force as necessary with a tool softer than brass...liike a chopstick!
