For those of us that use the Rollmaster brand true roller timing sets because they permit us to degree in the camshaft operating event, you should read this article that Ted authored and appeared in Issue 151 of the March - April Issue of Y-Block Magazine.
IF this article has already been cited in a previous Y-Blocks Forever Forum submission, I think it's appropriate for me (who missed it!) to bring the subject to everyone's attention again. Thanks to Joe Craine for his pinch bar modification recommendation to help prevent the problem from occurring due to damage to the timing chain when the timing set is removed to permit changing the timing set gear orientation for re-installation.
Ted article as it appears on his Eaton Balancing web site.
