|This tool is used to align timing numbers and marks to the crankcase parting line on Lycoming engines. It permits timing from the marks on the aft side of the flywheel. A spring clip holds the tool to the flywheel.|
No more straight edge for me, this tool snaps onto the flywheel, align the pointer on the flywheel and the other end of the pointer can be seen easily at the case halfâ€™s. Itâ€™s to easy to time the magnetos now.
