Timing Adjustment Key 4°
Product Description
Offset flywheel woodruff key allows a + or -4° overall timing adjustment by re-positioning the location of the flywheel on the crankshaft. Increasing the ignition timing can increase low-end power on stock to mildly modified engines. While some highly modified engines with high performance CDI's may actually benenfit from retarding the timing by 4° allow the engine to turn more rpm.
