: Double pumper shot tuning?

I have my car set up to leave at idle. The shot on the front pump starts almost instantly and last until the rear shot ends. I am having a problem fouling plugs when the engine is cold and I think it is because of the front pump shot. Would decreasing the front sqirter size and starting the second shot sooner with a bigger squirter work with my launch? Does anyone here run a bigger sqirter with a longer shot in the rear?
