Still toying with the idea of adjustable timing gears but I did a little calculating using offset woodruff keys and moving the chain one tooth at the camshaft. One camshaft tooth=20 deg of camshaft timing(at the crankshaft). Offset woodruff keys are available in 4, 6.5, 8 and 10deg so the 10deg woodruff would be half of a tooth. So I should be able to achieve any timing I desire within a deg or 2 by using the correct offset and moving the chain one tooth + or - if the timing falls outside the range of the woodruff key. Am I correct?
