Timing is mechanical and is 30 at total. I will revisit the springs to see when it's all in by. However too much timing typically will manifest itself in a white hot strap and not so much in the air fuel ratio. Regardless a good point to revisit. I have to believe that the vehicle is under part throttle (primaries only)at higher RPM for so long that is draining the primaries and not touching the secondaries. Further exacerbating the issue is that the secondary driver side jet is uncovered (turning left) when I do get back into full throttle. Going to 1:1 linkage should help the first issue as engine will pull from both primary and secondary and jet extensions will help the latter. FYI. This is a 540 HP 408w in a 3000 lb Griggs prepared 1986 Saleen Mustang. Cobra is gone now. I miss that car
