Mike,
I apologize, I forgot all about getting you some pictures of the cure for this issue. You need to increase pop off pressure of the inlet needle not decrease it which is what will happen if you shorten the spring. I've heard of some people stretching the spring slightly to make it longer with mixed results but the spring will eventually go back to its original length and tension. The right way to do it is to add a shim under the spring to increase its tension on the metering lever thus increasing pop off pressure. I recommend starting with a .020" thick shim and testing with that, increase in .010" increments if necessary until you get the desired results. A good pair of scissors can cut .020" shim material with ease, I used a piece of red poster board so you can see it easily.
