Spraying Seafoam directly into Honda 2000 Carb.

For best results, start and run the motor with the choke on. Do it for 1 or 2 minutes, every hour, for a few days. The choke being on will suck more fuel through the jet, creating a better flushing effect to get all the jets cleaned and devarnished.

If that doesn't work, time to tear down the carb and clean the whole thing up properly, with carb cleaner and a pressurized air hose in the jets.
