I do not think it is a timesert after all. It appears identical to the Spark Plug Rethreader Kit sold at local FLAPS. I used one of these 40 years ago with no issue on a 140. Any reason not to use again assuming I can get the botched one out?

Thank you Chuck.
It appears the problem was that they did not chamfer the hole, therefore the flange of the insert is not flush with the head.
Then it was overtightened, causing the flange to crack creating a poor gasket surface, as well as causing the sparkplug electrode to not extend into the combustion chamber.
Also, the length of the insert seems to short, creating a large void around the tip of the sparkplug.
