The majority of engines cannot do a 4-cycle
There never were a great many. The Fox 25 (3 bolt backplate models) -29-35, of course, the Johnson "S", Veco 35 Series 100, OS Max S 35 and H 40, Super Tigre G21 46 and V51 / 60. However, even in the old steel cylinder and iron piston days, other Johnsons besides the S, and various K&B engines, etc were used for stunt, but no 4-2-4 run.
Not all Fox engine owners wanted to run the classic breaking run, either. A friend who visits these forums, Jim Thomerson, ran his in a straight two-cycle, just not leaned out. It's the way that I run my various OS FP engines, what I call a "Rich Two Stroke", and you match them up with a very low pitch prop, such as a 10-4 for an FP 25, and an 11-4 for an FP 40, so that the prop is more of a speed limiter than the engine rpms.
