Read this again, Dave.

After about three tanks idling and three tanks on the other one running around and slightly leaning each run, we did a pinch check. Guess what?- the one that sat idling the pinch was nearly gone, the one run around it was nice and tight. This is why car engines are only warrantied for 30 days, not 2 or 3 years or even 5 years like one plane engine manufacturer.
Guys that break in a car engine the ABC way, usually are in disbelief until they realize that their engine is lasting 10 gallons of fuel instead of 2,3 or 4 gallons between rebuilds.
I once talked to the exclusive US importer of a very high quality, high performance (exceptionally expensive) car engine line from Europe, asking the owner why he recommended such an excessively rich break-in, telling him that the stated method will prematurely wear the engines out. He told me laughing "Thats why these engines carry no warranty, for every engine I sell, I will sell two piston / sleeve/ rod sets" and further went on to say "the car crowd has been conditioned to wear these things out so the parts business is real good,....If we told them how to break-in and run these things right, I'd be losing a lot of money"
...And your last post

...Wait a minute....this manufacturer says that it's a "fact that wear highly coincides
with high temperatures". The doomsday folks are saying that wear and damage
happens from running the engine too rich.
Do you think it could be Profi doesn't want some of the people that buy their engine, those that are 'smart enough' to listen and four-stroke their new engine (allegedly not possible in this type of engine).
How does '10 gallons, after an ABC type break-in, instead of 2, 3, or 4' go in the same paragraph with your (and Profi's) 'high wear coincides with high temperatures'???
Excessively high temperatures - that is for sure.
But more wear at the normal running temperature, than at a lower, high friction four-cycling???
Someone here is missing the point and I am not him!
