And why are you citing #1 cylinder? Are you under the impression that the ignition timing varies significantly from cylinder to cylinder?
If you think there is a significant variance of timing between cylinders, where could you have possibly gotten that idea?
On this radial, cylinder #1 is working with a master rod and cylinder #2 and #3 are working with a slave rod. That is the reason, combined with the S magnets at 120° - 120° - 120° the ignition timing is NOT the same for each cylinder. Out of the box, ignition for cylinder #1 is 45° BTDC (even this value is too high for me), and 52° and 38° for the 2 others. Best result for me is 30° BTDC on EACH cylinder. And that is unfortunetly not the case with this saito product.
Note : I have modified my engine to have 30 degrees BTDC and it works really smoother.
