Hey guys. I have an 83 Scrambler and I am switching carburetors from Carter Bbd to MC2100. My jeep has been nuttered, and the EGR and CTO are currently disconnected. When I put the new carb on, I would like to reconnect them. However, the vacuum diagrams for the MC2100 i find online always show 5 ports on the CTO valve and mine only has 2. Is there a way with 2, or do I need to purchase a 5 port? Any help is appreciated. Thanks!
