Here are a couple pics so you see what is under my hood. After receiving Clives advice I reduced the pump pressure further down to a little under 2 psi - seems to help. The floats or the power valves did not leak when I tested them on the pump at 2,5 psi. So now the pump delivers less which will lower my float level a bit more but still the car drives nice and with crisp response, no stumbling when warm but needs a bit of choke for the first mile - just what I expected. If I cannot stop the smell I need to find a way to keep it out of the car. My exhaust pipes run straight under the car and end about 3" after the rear bumper. I took great care to make sure the headers and the tubing going rearwards is gas-tight. No leaks under the car. I ducktaped all openings on the floor or firewall but I can still smell a little bit when running with open windows and slower than 40mph. At 65 and above the car is probably too fast for exhaust fumes to enter or it runs lean and clean at those speeds. The plugs are a nice brownish color so its not on the edge..
