Float Level
hey, i'm not sure if i'm able to help, but i will tell you how i set the float level on my bike.
I take the carb off of the bike,
Remove the Float Bowl,
Inside Is A Little Needle, called the Needle jet.
when you pull back the acellerator there is a little peice of metal, which when you pull on the throttle this peice of metal drops, letting the needle jet fall down farther.
you can slightly bend this small peice of metal so that not so much petrol/or more petrol will flow through the Carb.
Also, you may find your needle jet to be sticking, if you take it out and gently sand it down, on all of the edges, and then test the needle jet to check it falls through smoother.
When you put the float bowl back on the carb, ensure there is no dirt inside the float bowl, of it could jam up your carb and cause your bike to start poorly, and cut out while ticking over.
I'm not sure if this helped you or not, i'm only 14, and just starting to get into this sort of stuff, but, if i havent helped, maybe you can look back to this for future reference.
Hope I Helped.
