yes use a tach to check the engines max and min rpm to set them to within specs to prevent stalling or running lean/damage after giving it a tune up and checking the air filter for cleanliness
Homemade Log Splitter Issues

All thread..... threaded rod.....the stuff he used to fasten the engine and pump plate together.
"All thread" = "Ready rod" 
Must be one of these dialect issues. I've never heard that term.
I have always considered that rod to be unsuitable for almost anything mechanical except maybe hanging stuff from the roof of a building. It is consistently weak and soft, as fastening hardware goes. I've never heard of grade 5 or grade 8 versions.
I'd sure try to find something else to hold a log splitter together.

There's a wide range of grades of threaded rod available, but you're not likely to find it at the local hardware or big box. They're available from McMaster, and I assume Fastenal or a good industrial supplier (if you're lucky enough to have one). Maybe Grainger.I have always considered that rod to be unsuitable for almost anything mechanical except maybe hanging stuff from the roof of a building.

Grade B7 is not awfully expensive and comparable to Grade 5 cap screws.
Grade BD is more expensive and has properties similar to Grade 8.
Both also have much better quality threads than the sloppy, ragged threads on hardware store all-thread.
I'm also uncomfortable with the way that pump is mounted, but my gut feeling is that if doesn't noticeably twist or vibrate under load, you might get away with it. There may be something better available here:
https://www.magnaloy.com/https://www.bsfinc.net/products/adaptorsThe cast aluminum Magnaloy adapters are inexpensive. More choices available in the fabricated steel adapters.
Where would folks add additional support? I don't want to weld on the threaded rod, as it couldn't be disassembled if I do that. How much time should I spend on the possibility of catastrophic failure of the pump locking?
Key sheer is preferable, or hopefully it just stalls the engine. A pump locking up should really be the last concern in a hydro system, they don't just go boom unless something else happened to make them go boom.
Zero more time, that's just your weak point.
