Default RCMK K30 motor

I need help.
I have a pair of RCMK K30s and they are counter rotating pairs.
How do I visually tell which is rotates clockwise or counter clockwise without starting them ?
Thanks in advance

Do they have a "pull start" on them? If they do just pull the cord and see which way the output spins.

RCMK 30cc Assault mono.
The carbs should be on opposing sides, the easiest way to tell. Counter-rotating (normal) the carb should be on the right side.

RCMK 30 cc.

Check where the primary coil is. I only had the 26 cc RE RCMK. The problem with the 26 cc was that they made several version of the RE engine. I don't know if RC Marine Korea will be any help or not.

One should have a R printed on face of flywheel. The right hand counter rotator RZ style usually has left hand threads for collet and on flywheel. Try threading a 6mm bolt in crank. The one it fits it the normal left hand one.

Are they R engine or RZ.

The R of course is different the collet bolts in the flywheel and flywheel is in back. The coil location being right or left for R or RZ will tell you to.

Go on RCMK Korea you can see pics of them all.
