River-Pete Posted May 23, 2012 Share Posted May 23, 2012 Hi The first thing to do after the winter.. Fill the tank with "fresh" gasoline. Today's gasoline will go "bad" after a few months, resulting in uneven firing and coatings inside the carburetor and the Jet´s. A properly tuned carburetor reacts instantly to poor quality gasoline, causing rough idling and intermittent loss of power. If that doesn´t solve it.. imao, You probably need to clean that carburetor. Unscrew it and clean it thoroughly, making sure the Jet´s and the float chamber also get their share of the cleaning.. Start with refueling tho.. and next fall leave it with an empty or close to empty tank. Even better is to drain the carburetor before it goes into hibernation..
