I just got my Chrysler 70 hp cranked. I had replaced all the fuel lines except for one line that was a different color from the rest. It had a tiny metal piece inside the tube. Looked like sometyoe of restrictive piece. So I replaced that line and it cranked right up! But once it cranks it immediately revs up high, complete tops out! I haven't ran it longer than a couple seconds cause of how high it revs.. What could the problem be? What is making it rev so high?
