My 72 coupe (base motor) came with the distributer oriented so that the tach cable connection was facing the firewall with about 2 inches of clearance. (Distributer band has the correct part no. and date code.) The previous owner had tried to connect the tach cable, and because of the sharp 90 degree turn out of the distributer, the cable broke. I too bought a cable, installed it, and forced it to bend sharply when exiting the distributer. The cable was jammed against the firewall, but the tach seemed to work. I took the car out on the street and found that the tach needle would not go above 1500 RPM. After about three minutes of driving the cable broke.
I bought a cable repair kit, and I turned the distributer clockwise one cylinder, and I moved all of the plug wires around to compensate. The tach connection now points at the drivers side seat, but the vacuum advance connection points towards the passenger seat, and it is jammed up agains the plug wire shield bracket. (I could not turn the distributer two cylinders which would have been better for the tach cable because the vac advance unit would hit the firewall.) I repaired the cable and reconnected. The cable still had to snake in an "S" pattern out of the distributer, around the back of the shielding bracket, and into the firewall. When I started the motor I again found that the tach needle would not go above 1500 RPM. I immediately disconnected the cable to avoid another breakage. Questions: What is the correct position of the distributer? Could something else be broken that would prevent the tach needle from going over 1500 RPM? Thanks.
