I am unsure, but my intuition tells me that it is not an intake port problem...... but if you are correct in your analysis, test it:
Take the cylinder link off the pedal, give it a full stroke, reattach it and see if that does the trick. Then you will know, once and for all.
I am excited to hear, don't keep us waiting!
