Hi,
I updated the RR SS I (1973) with 123tune +, hard time to find the correct curve..
A: Changing the coil (Pertronix Flame thrower 1.5ohm) and ignition wires (Pertronix 8mm) on a RR is quite a challenge, we got pipe everywhere (hydraulic, electric, fuel, airco,... ). Takes me 2 days.
B: When started engine, I got noise like a tractor, like if some cylinder don't fire up... check cables with ohm meter and everything sounds good.
C: Try to change advance from 4% to 5% and sounds much better, should I try to 6,7 or 8 at 500RPM ?
any suggestion ?
Dear Mr. Duvivier,
I would try 8 degrees and double check if all ignition leads are connected in the right order.
Best regards,
