The line that is now hooked from the pump to the return hose is meant to feed into the forward facing fuel hose barb (this is the inlet for the accelerator enrichment pump) and the other barb connects to the return line. Those monkeys... Without the accelerator enrichment pump you will have a flat spot on take off. But be warned, there might be a reason why it's not connected (your pic does show a new diaphragm gasket poking out around the top of the pump). Reconfigure the hoses so they are correct and see what it does. Use the method I suggested in my earlier post to look for the tell-tale stream of fuel coming out of the enrichment jet. If the pump is functioning and all the diaphragms and gaskets are new, it will shoot a solid jet of fuel straight across the primary throat in the carb.
