The carburetor on your engine is not adjustable. EPA regulations have limited the current carbs to where they are set from the factory and that setting is â€Ε“the” setting. You’re best bet would be to get some carb/choke cleaner and go through the carburetor with it. You may also want to get a very thin wire to clean out the jets in the carb with as well.

Usually cleaning the carb will work pretty well and should alleviate the problems it’s having.

Thank you for using Manage My Life!
