Thank you so much Zeke for your response! I'm happy to know that this is something that I can probably fix by myself (trying to save some money here) but unfortunately I have no clue what you are talking about when you talk about the carb. It sounds easy for you but for me this is chinese. LOL! But, I love a great challenge and I will try this option first. Who knows, maybe one day I will be the one answering these questions for other people.
Could you maybe give me possible reasons for the noise coming from the air filter?
