Yeah... that's more or less what the Clymer manual suggests. Clymer is popular in the US. Here not so much. Clymer makes a big thing of this float adjustment, the Haynes not. Is that why so many in the US believe there's something wrong with the float level? In the European fora 'the problem' is hardly mentioned if at all. I am fully aware that with unused carbs that have been left with fuel for years and years you may see a problem. But in Europe we have the experience that the float sytem is very reliable and - like mine - functions flawlessly for decades without ever needing readjustment. It's just not a regular maintenance thing. Over in the US there seems to be a problem. My feeling is that the problem is caused by owners themselves who - eager to do 'maintenance' - have read the Clymer manual.

Clear tube a reliable procedure to verify if the floats fload fuel and cause bad sooty idle killing plugs.
My K2 build got a very sooty smokey start despite I had tried to set floats correctly. Just a little too high real level and what a smokey start! I just bent the tabs a little and case solved.

I did a fine tune later with a set of extra bowls, 1 of each model.

My K6 with TMR carbs have started to soot 1-2 that I know had high levels before without floading which they do now. Clear tube plug tools earlier purchased

This fits TMR carbs too

Yep, float level is NOT a maintenance chore. Float level never needs to be messed with. Stop doing it . ( Except the P.O. 'prolly messed with it anyway, so ya better check it one time.. lol . )
