Take a look at the carb and figure out the make and model. Then
google "rebuild + make + model". Should come up with something
useful

Probably be a good idea to research the common factors causing
high hydrocarbon readings first. There may be other things besides
the carb that need attention e.g. fresh plugs, clean air filter, fresh oil,
ignition timing etc.
