I know that they are for the choke, but I pulled the carb off to rebuild it and one of the tubes came out of the base with the carb. Is this a source of vacuum??? Should this be a sealed air tight connection? If I take this off will it affect anything? Help!! I am not familiar with a 2150 until now!

The plate that bolts to the manifold can be a major source of vacuum leaks. If the carb is off, it won't hurt to pull the plate off and put a new gasket under it.

Is there an intake port directly below the plate. If so then the tubes are pulling vacuum. Not good if the tubes just pull out of the plate!! Both tubes will pull out with little effort. I am going to pull the plate tonight and find out what is under it and if it really pulls vacuum through them!!

the tubes are coiled like a heating element under the plate. there is no vacuum being pulled through, as the tubes never are exposed to it..the air goes in one tube, warms up by going through the coil, and goes out other. They are supposed to pull out. As long as there is no laeks around the plate itself, you're fine.

If I am not mistaken the tubes you are talking about supply heated air to hold the choke open after the engine is warmed. The initial choke opening is electric and is shut off after the engine warms, then hot air takes over. Some of the other guys probably know better than I, but I am pretty sure this how this system works.
