Set the FUEL level and forget about float height.  Yes, changing float height will change fuel level, but what's important is fuel level.  A carb could care less where the floats are or where they should be.  All that counts is fuel level.

tms are around 18mm.

I always kinda thought that you set float height to set fuel level.

float height does set fuel level IF its within 15 degree of 'level'(parallel to ground).

While searching for something else I just ran across some Mikuni info for TM float height: 17-19mm for TM32, TM34, TM36
