Before I would let a Cat tech work on a small 3 cylinder Cat engine I would call up my local New Holland/Case dealer and ask them about any issues. I would lay dollars to doughnuts they will know more about the small 3 cylinder Shibaura engines than a Cat tech that works on big monster engines every day and never has even seen one of the little "Cat"/Perkins/Shibaura engines in his shop. The only thing "Cat" about these engines are the stickers and the paint color. My dad owns a little 3 cylinder Shibura/Case compact tractor and they are killer engines. Never a lick of trouble. Very powerful with lots of torque.
I honestly already knew this but had a senior moment, anyway I did just get off the phone with a Scag technical specialist, and he did verify that any warranty work performed on their 28 hp Cat diesel must be performed by a certified Cat technician. I would think the 35 Cat diesel used in ZTR applications was also of a Perkins design, the tech is going to email me this information, he was also interested in knowing about the 35.
Cat bought Perkins somewhere in the later 90's I believe, but because of the European market being so diehard Perkins they left everything in Europe as it was before Cat purchased the Perkins operation. I guess they used the old philosophy, if it ain't broke, don't fix it.
This is interesting reading on Perkins:
