M35 Valve Adjustment

Our M35 has an annoying ticking sound at idle and I am presuming the valves need adjusting.   On the sea trial last year our surveyor did not think it was anything to be concerned about but to is beginning to bug me.   

The actual adjusting procedure is straight forward enough but what I am unsure of is how best to turn over an engine with no compression release and no accessible hex nut to turn with a wrench.   The 30mm nut on the crank shaft has a bent up keeper that precludes using a wrench.   The 18mm splined shaft offers a possibility if I manufacture an adapter or the pulley has three tapped holes that I can adapt to.

OK, there must be a simple solution.   Am I over thinking this one?

I adjusted the valves on my M35BC, but that was 7 years ago.  Did it because the engine wasn't doing full RPM's after I changed to a Maxi prop.  Don't remember having any trouble turning the engine over by hand.  I do remember having trouble seeing the flywheel pointer.  I used a flashlight, mirror and best guess.  Must have got it right.  The engine idles smoother and revs better than before the adjustment.  Even though I adjusted very little. 
Hope this helps and good luck.

Your compression is higher than mine so maybe I can spin it over easily enough.  thanks

My grandfather who owned a garage always said a valve tick on an engine w/o hydraulic adjusters, is one of the sweetest noises you can hear.  It means the valve is closing and the seat not being burned by exhaust gasses.   :rolling
