Another ground out a piece of a 30mm socket to form a wrench and braised on handles!! These be some manly men or at least clever mechanics. Nevertheless, just how I was to use this screwdriver or where I could buy this “3rd wrench” was not altogether clear.
So, the next morning I tried the adjustment ordeal again. The “large flat screwdriver “did just fine, thank you. At the risk of pissing someone off, I really don’t see the need for a third wrench. Now, I am going to explain; the valve assembly (involved in the adjustment procedure) has 3 parts not 2, as leathermang pointed out. There is, off course, the top nut or adjustment nut, the jam nut that compresses the valve spring, AND the hexagonal valve spring retainer. Every once in a while, by my reckoning, when the jam nut is being adjusted to create more clearance (lash), the valve retainer will also turn. To stop this spinning, take a large flat screwdriver and align it with the cam bearing mounts so one of the points on the hexagonal valve retainer is impeded from turning. With the valve retainer will no longer turning, the jam nut can now create the proper gap. Joe Marroso

Not exactly the secret handshake yet... and this stuff IS in the archives if you look good enough... where to find the wrenches, everything....
But the description for the secret handshake is that the valve is threaded on the top, either of the two nuts used to adjust the valve lash can be stuck so that the VALVE turns ( the retainer only turns because it has a cleat which goes into the mortise in the valve ) when you try to move those nuts. So if one or both of the nuts are really stuck then you can use the retainer to hold the VALVE with enough force to unstick either of the nuts which are tight.
You seem to be giving the impression that the screwdriver is an acceptable tool for this job and that those suggesting the third wrench are somehow spendthrifts or unable to use a screwdriver well... when in fact you have dealt with very few stuck nuts on these engines and it may be that the amount of abuse a stuck nut has had in the past may put the force necessary to move it in a different league from the ones you have experienced first hand.
