Adjusting the Valves on a Small Block Chevy Engine

I found a rebuilt carburetor that was cheap enough it was worth it vs. rebuilding myself. It turned out that the PCV connection to the new carburetor was smaller than on the old one. I don't have a lot of parts leftover from Romeo, my old Rambler, only three. One of them fit perfectly in the new carburetor on Isabelle for the PCV connection. Here is the part from Romeo I used sitting next to the new carb:

You can see the same part on the flathead at the base of the carburetor here. You can see the new carb installed in a really wacky color setting for my camera that I don't completely know how to use yet:

I readjusted the timing and got the engine warmed up. Adjusting the valves does not require feeler gauges. What you do is get the engine at running temperature and stop it. Remove one valve cover. Put special clips over the rocker arms to keep oil from spraying all over (see below) and start the engine. Then you loosen the nut on the rocker arm until it chatters. Tighten it down until the chatter goes away. Then, you tighten the nut a quarter turn. Wait a bit, and turn another quarter turn. You can hear the engine change in sound, then adapt, as the lifters get used to the new setting. Wait until the engine sound recovers before tightening again. Do this twice more for one complete turn tightening. If you click on the picture below you can hear the engine running and see the rocker arms rock:
