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!

The 2 port will work fine, if it operates. The inner port marked S goes to ported vacuum. In stock form it went to the Temp Valve on the air cleaner. You can hook it to ported vacuum in the 2100. The outer port, marked E goes to EGR.
