*13* is correct. The one bar system connecting the left and right bank is not geometrically correct. Mike Pierce of Pierce Manifolds told me to go home and draw the setup to scale and watch the movement. I was astounded to see 1/8 of an inch difference in travel from side to side. I changed to a center bell crank that I made with 2 bearings to reduce the wobble of the bell crank. I took a measurement with 2 dial indicators and my side to side difference is .007 in. Thats not to say every thing is great. I'm still working on the tune.
