Yes, it sounds like the float may be sticking or the float valve is not sealing properly. If the machine has been sitting for that long I would suggest doing a thorough carburetor clean and rebuild which will take care of your problem.Thank you it has been a pleasure to assist you.Please take a moment to rate your experience
