Hello everyone. I recently bought a project X1/9 that has been sitting for several years without use. I decided to pull the carb to give it a good cleaning. All hoses and wires are disconnected along with the four corner nuts on the carb base and throttle linkage. With all of this removed the carb is loose, but feels like there is still something holding it to the intake manifold in the center. Anyone have any idea what the problem may be? Thanks for any help
