I just got finished redoing my lower unit with new seals and new pump and i also realized over the winter that I had two intermediate jets wrong. I put it all back together today and i can't seem to get the idle down. Its at 1000 RPM on the muffs but i got a cloth over the prop to simulate back pressure. I checked both throttle plates and they are closed completely. I even pushed back the adjustment screw on the slow speed timing and it sits at 1000 RPM. Before I retarded the timing it ran at 1200 RPM. Shouldn't I be able to kill the engine by just retarding the timing? I didn't have this problem last year because the jets were wrong on 2 cylinders and it would sputter and die. Any help with this issue would be great. Thanks.
