Reverse rotation predator

[Dualfuel (Bruce P Jackson)]

Has anyone ever seen a kit to build a reverse rotation predator?

[DennisP (Dennis Pecynski (Ohio))]

why do you need a reverse rotation?

[r_wesseling (Rindert Wesseling (Louisville,CO))]

You may not want to reverse your Predator. A lot of modern engines offset the bore above the crank to reduce friction during the power stroke. Just something to be aware of.

How about taking the output from the blower side?
