You do a great job explaining Carburetor functions. You should redo these videos in HD with close-up shots.

Thanks for this video! Just a question.. what will happen if the float is higher than specified? will enrich the mixture? Thanks in advance!

[@freestyla101]

Yes it will. The higher to fuel level, the more weight there is being pushed down by gravity.

Excellent - and Thanks Moss Motors for having the metal tab adjustable floats - others have the non adjustable and they cause overfill, at least with my carbs. I can't find washers that fit the valve.

Helped me visualise things better in my bike, thanks!

Thanks for that, very helpful.....

Any input on those nitrophyl floats? I see they appear adjustable but are they better than the brass float and fork setup? What I recently discovered is fuel had seeped in to fill and turn one of my plastic tabbed float setups into more an anchor that a bob. Cheers!
