Here is what I have found about your carb. The original carb for your engine was #632107. This was an adjustable carb. It was superseded by carb #640084H, which is nonadjustable. If you do a Google search for a Tecumseh adjustable carb #632107, you will find that they are still available out there. You must be very careful, because some people and businesses say they can get you one, but then try to make you purchase the nonadjustable one. BE CAREFUL. If you would like to rebuild your existing carb, the rebuild kit is #31840. I recommend that you contact the most trust worthy repair shop in your area and work through them. Make sure that you explain exactly what you want done. Hope this helps.
