Put a heavier spring in the vacuum advance pod. You can get a quick change kit to make it easy. I think quick fuel makes a kit that removes that pod and replaces it with an easily accessible screw. It won't snap open and give that sudden boost.

Even with a heavier spring, you will still open the secondaries. Still doesn't fix your original problem.
