Hey ford.tobey. The carburetor might be varnished – usually caused by leaving fuel in the system for too long. The metering needle, jets, etc., may become clogged or glazed with the old fuel, which tends to become sticky (like varnish) and sneakily alters the prescribed air:fuel mixture. This is one way you can have a lean mix, as “cgulyash” indicated in his comments earlier. The fix for this is cleaning of the carburetor, or rebuilding it. Whether or not you can do this on your own depends on your basic mechanical aptitude and your ability to follow the instructions to do the job. Some basic tools, spray carb cleaner, and an assortment of fine wires (compressed air helps, too), and all you need is the step by step instructions easily (normally) found on line. Good luck!!
