Jeff1.......be careful when you go to remove the carb. Remove as much of the sealant from the base of the carb, and completely remove the pinch bolt assembly and sealant. You've pretty much made an air tight seal which is fine. When you run the motor for an extended period, the RTV will get hard. The carb barrel(the part that goes into the engine) is composite with an aluminum sleeve bonded to it. If you twist and pull off the carb you may leave the aluminum sleeve inside the engine.
