Setting tappets with "Clickadjust"

[Bendy toy]

The Gunson Gunson Clikadjust Tappet Adjuster has been around for years. Has anyone tried one on the GS tappets and do they work as well as advertised.

Ah, there will be a slight problem with using this on a GS :

Valve clearance is easy to adjust on all push rod engines or OHC engines with top adjustment using a screwdriver slot and locknut.

.
Last time I adjusted mine it needed an allen key to turn the adjuster; otherwise, sounds like a simple solution.

The principle is quite simple, nip up the gap then back off the adjuster by a fixed fraction of a turn. If the thread of the adjuster is cut to 1.0mm per turn then backing off 1/4 turn will give a 0.25mm gap. Backing it off by 54 degrees = 0.15mm gap (inlet) and by 108 degrees = 0.3 (exhaust), not so easy to measure though.

If the thread is cut to 1.5mm per turn then 1/10 turn (36 degrees) = 0.15mm and 2/10 (72 degrees) = 0.3mm ...

Feeler gauges might be easier though
