    I believe I already offered my opinion on that. (grin) Removing the head building a fixture makes finding the piston easy.

    Orient the dial with the relationship of the foot required to engage the piston, so that when you tighten the spark plug adapter and rig everything, you don't lose that relationship- ie the foot engages the piston, not offset. Once the tiny screw falls out of that foot, you'll need to pull the head anyway. LOL.

    Having fabulous spark is the easy part. Having it at .090 BTDC on your HM 80 is the hard part, and why we use those dial indicators.

    And a little “after done” knowledge I happened across....which you probably knew....for hm 70 and up engines you need to put a 10 degree bend in the foot to get it in the head....if you choose not to remove the head which I’d never do...lol...lessons learned....
