Probably 99% of all of these Listeroid engines are used in Asia and Africa. In most of these end user places there is no such thing as a fork lift truck or a delivery system - particularly at the end of the track where the farmer will be using the new engine. So, any kind of truck that is cheap and available will be used to deliver the new engine to its destination. Forget any kind of fancy systems of levers and pulleys and cushions to get the engine off the wagon. The driver and his mate will manhandle the crate to the side / end of the truck and then push it off. They will not look for a soft patch of earth for it to land on. Once it is off the truck their responsibility is complete and they will drive away - leaving the farmer to "somehow" get the engine to where he wants it.
If 99% of all these engine survive this treatment and keep going without any air filters or oil changes - for years, then there is a very good chance that yours, which has been positively cosseted in its delivery to you, will be just fine.
Not sure what a dial gauge will tell you. the chances are that ALL these engines have a high degree of run out. If you DO check with a dial gauge - please set your action standards BEFORE you measure. What are you trying to achieve ? What level of run out is acceptable (and how will you know). If you find run out greater than your action standard, what will you do about it ? Sometimes, it is better to just run the thing and not give yourself sleepless nights worrying about things that are of little consequence.
