Hey akk,<br />I'm trying to set the timing on my 1992 Merc 60HP. The manual recommends using a dial indicator to find TDC, then backing off to get to 0.451" BTDC. I'd like to find a dial indicator with a spark plug thread adapter so I don't have to 'rig' a holder on a normal style indicator. I haven't been able to find the tool I'm looking for at Grainger, MSC, McMaster-Carr, or Snap-On. Does anyone have an idea of where I can find this tool? (There is a picture of said monster in manual, too!).<br />Thanks, Rich
