Maybe your membranes are dammaged ?

What carburettor have you got ?

if you cant start scooter when its hot membranes are gone...

check carb setting... best way to see if all is oke is to look at the sparkplug color... i guess its all black and greasy if it uses more gas...

then there is only one solution... wrong carb set.. try to put it in stock setup... watch for jet size and the position of the ring on carb needle

Sparkplug is ok,color like white coffe,now I"ll get a lot of new parts,then I will see what about gasoline.
