There may be an air leak in the fuel path. Make sure the inlet (high speed needle housing) is sealed properly. Make sure the fuel pickup is in tact and not sucking air. I take it that you are quoting your temps in F and not C? I had a similar issue with one of my O.S. .12 engines that had a leak at the HS needle housing as they can be a little delicate when tightening.
