Spinning cylinders and crankcase? Does the gas tank spin, too? If not, it seems that sealing the junction between non-spinning fuel line and spinning fuel line would be a challenge.

As for the gyroscopic precession - you can go ahead and ride it first, I don’t mind. Really. It’s OK.

It’s a brilliant design. The air/fuel mixture is fed into the crankcase and piped to the cylinders. These engines had no throttle, the pilot used a coupe button to cut off the spark when he wanted to slow the engine. You can see the induction plumbing in the picture below.
