the dellorto carb is easy to clean, so it'a good idea to get used to working on it.
to clean a dellorto carb
switch of your fuel valve.
then unscrew the carb from the manifold and slide it out. it now dangles.
remove the plastic airbox. pry out the metal screen. squirt some carb cleaner all over it. look inside the carb. does it look dirty? spary carb cleaner in there.
turn the carb over. unscrew the two smaller screws on the float bowl. some gas should pour out over your fingers.
look at it, see if it looks dirty. give it a squirt or two of carb cleaner for good measure.
unscrew the gold main jet. hold it up to the sky and see if you can see light come through it. give it a squirt of carb cleaner just for good measure.
now, unscrew the top two small screws and slide out the throttle cable. look at it. does it look dirty? squirt some carb cleaner in there. shake. let it all drip out. squirt some more for good measure. reassemble in reverse order.
