I don't think that will work. It is only enrichining the mixture during the start. The valve will just make the car run rich if it were rigged to do so. There is no extra air going into the engine, so the extra fuel would just pass through unburned.

From what I can remember, this valve only functions while the starter is engaged and then shuts off.
