Thought I was having a senior moment when I first saw Broady's timing disc. Very confusing for a novice. Quite why the timing marks are shown clockwise of TDC I do not know. Perhaps his printer got a mirror image to work withDazza wrote:Are you using the MB Timing Disc?
Is it me being a thickoor is this misleading:
I fell foult o it the other month marking my BTDC clockwise to TDC because of this disc (schoolboy error I know but...)
