Thanks for the youtube clip;

I can see your confusion there…

• Did you already use a new rebuild kit ?
• Did you use new floats from us , as they are factory adjusted?

7mm = This is when the float is actually resting on the “needle” plunger (If you press down the float, it will drop to 4-5mm ish)

The spring is just there to make sure bumps , shocks , etc doesn’t cause the float to ram the needle against the golden seat (well)

17mm is when the float is lifted up to the ceiling  (as that would be how the carb is when it’s on the bike) , until the float bowls fill up with the float going down to 7mm to close the fuel delivery.   (it will hover around that number as you ride as not to completely drain the carb in full throttle)
