I have a gilera DNA 125 . And it won't start . It's got fuel going to carb and as a good spark batterie is good but ju0776130935st won't start also as good compression
take out spark plug, dip in petrol, refit and see if engine fires, if it does, check the carb jets for water or blockages, that the float and float needle isn't stuck, also check the choke is working at all.
