Great engine right there, i put a carb from a 900 series briggs & stratton, takes a little finagling, but i think you have to swap the exhaust too, i put the exhaust from the briggs on mine too, i had to remove the heat guard so it would fit in my frame, not sure what you will have to do. but any carb for a 10 hp/the cc will do, make sure you get the correct bolt pattern tho, if you dont you will be dissapointed, carbs are made to be level so it cant have tilt to it or it will either flood or have no fuel in the engine, for the 900 series carb i had to bring the idle screw down a little to start it, but once its running it runs fine, just doesnt like starting on a high idle
