Thank you, Jofaur86. How remarkable that the cylinder walls are so thin on so large an engine! (Then, too, I had never seek on of those Cobi Kits put together. That looks perfect for a grandchild at the right age.)

Remember that is is a gasoline engine, not the farm tractor Diesels that you might be more familar with - very low cylinder pressures compared with a Diesel engine, especially given the low Octane petrol that it would have been designed for.

I am however looking at that fancy coating on the piston crowns and thinking that they did that because they could, not because it was needed I've heard of ceramic coatings for racing applications (and the down side of that was that the ceramic coating flaked off and ate the turbocharger!), but that Tiger is never going to be thrashed to with in an inch of its life and is therefore pointless, unless it helps prevent piston coking due to the sedate nature of the musuem's use?

[Herr Dr. Professor]

"...unless it helps prevent piston coking due to the sedate nature of the musuem's use." You may be correct about that purpose. Back in the late '60s, the Milwaukee, Wisconsin police would take squad cars out on the freeway at night to "burn out the carbon." Of course, I am sure there were other purposes, too, such as "to see how fast this thing will go." Same with the city buses, only a bit more sedate. Hmm... Then, too, I remember that my mother's big ol' Mercury didn't carbon up much. Ahem.

It could be an interesting topic of conversation in the office tomorrow with the Piston technical specialist
