In the below service manual for a Kymco Agility 50, they show adjusting a carb float holding the carb upside down. They take a measurement with the float valve facing you with your measurement device "parallel with the main jet."

However, when I do that, I'm not even close (the service manual's 17mm is marked with marker on the ruler):

After talking to other people and reading tons of forum posts, I see that a lot of people flip the carb over and hold at an angle where the metal tang just makes contact with the float valve pin. However, when I do that, the tang already "just makes contact" when the float is extended its very furthest (part of the float has a built in tab to prevent it from going further). Still though, while being extended the furthest possible, it still falls short of the 17mm the Kymco service manual says it needs to be adjusted to. As you can see, I'm taking my measurement parallel to the main jet.

I tried measuring from the end of the float as well, but still doesn't seem to add up.

I talked to a mechanic at my local shop who said it could be a typo in the manual. If so, the 17mm is repeated more than once. He also noticed that the bolt pattern on the bowl in some of the pics didn't exactly match mine, so maybe those measurements are erroneously for a different carb. Any ideas on if I am doing something wrong? I've also read in different places that plastic floats aren't adjustable. Would appreciate any advice to help me feel confident I got the measurement correct before I put the bike all back together. Would prefer to get it right now since there is a foot of snow on the ground vs. tearing into again when the weather's nice!
Thanks!
