Hey everybody, I have a 55 with a 1f engine and can't find the TDC mark on my flywheel. I have the timing mark but nothing else. Any idea what that is all about? It is a 68 motor if that makes any difference. I am trying to set the valves and really need to know what to do. I helped an fellow cruiserhead do his valves this weekend on his 2f and it was simple. I know there are other ways to do this without the TDC mark on the flywheel. If anyone has any idea what I need to do please let me know. I searched last night but couldn't find anyone with my exact problem. Thanks
