Alright now I'm more confused. I replaced that exhaust gasket between the manifold so now it's recirculating some exhaust gases but the best mix is still all the way in. I even re-rebuilt the carb and it's perfect this time. What is wrong? could it be having a loose idle tube (the tube that is that picks up gas that sits in the fuel bowl)? It doesn't seal very well at the bottom so could excess gas get in by the idle tube at the base?
