If you dont have the special tool that measures the float level you can take a piece of cardboard and cut it to fit over the float |---| the arms should touch the carb body on each side and measure for the height the manual says it should be, tilt the carb sorta sideways to make the float rest lightly on the needle valve top spring. if your measurement on the cardboard is right and your float is right it should match up, if not bend the tab on the float till it matches the correct measurement on your homemade tool

Greetings:
Great idea Mystic. If'n you can write up that float measure tool design and post pics and specs, it'll be in Tech Docs for posterior-ity.

mystic its kind of hard to follow what you are describing...
if you guys were to draw a line on my float bowl marking max fuel fill height, where would that be?

I was watching a few videos on youtube about float adjustment
So if I have the carb off the bike and drained...
1) Flip it over so the floats are just hitting the spring
2) Measure the distance from the top of the float (really the bottom when its right side up) to the level surface where the float bowl mates , that should read 26mm?
can anyone confirm this to be the correct procedure?

dang mystic what a great write up, thank you for that. 2 questions
your last picture... seen here
1) based off of what you wrote, if the floats were just lightly sitting on the spring, shouldn't the floats need to come up a tad in that picture to hit your line of 12.2mm? right?
2) where can I find what level I should be at if I have an aftermarket carb?

yea hahah that carb is one I bought at an auction it was the cleanest and easiest to get to, its a yinba carb for a go kart i think. I dont know what the float level is supposed to be on it probably 12mm 12.2mm is the spec for the sa50 i was using as an example. If the carb were the sa50 carb the bottom would line up evenly with my marks

I am not sure what the level is supposed to be for your OKO sorry

Yes, that measurement is useless on your OKO carb.

I understand that , just wondering where I would get this measurement from?
The box the OKO carb came in is no help either

a quick search online says. 19mm from carb base to top of float ( bottom actually) the pic showed a 28mm oko, another page said same for a 21mm. seems like 19mm is the oko standard.

I used to have a link to the OKO service manual but lost it in the last crash of my computer because I was stupid and didn't back anything up for about 6 months on my standalone 2 terabit backup hard drive.
