Thanks for the response guys. This particular engine is on an OLD military plane that a neighbor kid brought to me. It belonged to his late grandfather and has been in an attic for at least 15 years. He only has the plane and engine and he wants me to get it flying for him, so I've put in hardware,servo's, radio gear, etc and have got it just about ready to fire up. I was unfamiliar with the engine and carb so thanks for the info.
I'm also going to post a pic of the plane in the begginners forum because I can't identify the plane. It looks to be a replica of some low wing USA jet similar to a U2. The word Komet is written inside it but I can not find any aircraft pics that match it. Its wings are stryrofoam covered with balsa sheeting and the whole plane has some kind of hard enamel type coating. It has "SFA 14252" in big letters on top of the right wing which I think might be a registration from some old model club. Any how, thanks again for the info on the engine and carb.
