Stihl 090 3 cylinder radial engine hotsaw.
This saw builder then made a bigger hotsaw with 4 Stihl 090 66mm Mahle cylinders.
He went to all the trouble making a gearbox to reverse the engine rotation when he could have just reversed the ignition spark curve.

Sounds good in the video but he needs a much larger log to make it work properly.
Better yet replace the 4 mufflers with 4 expansion chambers and it'll rip through that log.
