Clik-Adjust Rocker Gap Setting

I’ve had this tool for many years since I had a Reliant Scimitar and not used it since then.
I had a noisy tappet and wondered whether it had worn to a concave / convex shape which feeler gauges would not correctly set a gap.
After a bit of practice i got the hang of it.
I used a 15thou feeler gauge to check and there were a couple of tappets that felt tight but i could still get a 13thou gauge in. Reset them and still the same – so they may be the ones that had worn with a curve.
Job done and the engine definitely quieter.
Will use the Clik-Adjust again.
