Here's the method:
- Start the engine and bring to operating temperature.
- Keep 1 hand on throttle and start spraying in a controlled manner inside the carb (Air filter assembly removed)
- Let off the spray as soon as the engine bogs down and increase throttle so that the engine doesn't stall.
- Repeat above steps a couple of times.
- Turn off the engine, spray all inside the carburetor and leave for 5-10 minutes.
- Start the engine; it might take a bit longer to start so increase throttle to start.
Repeat the spraying process one more time.
- You're done!
Please note that if there is some other problem with the carburetor, like float adjustment or clogged jets, this might not work. Other possible issues include stuck butterfly or leaking seals.
