Can anyone please advise ?
I am mounting an OS 70 Four Stroke into a 3D machine, it will fit inverted inside the cowl perfectly with only the pipe sticking out.
But - I have heard that 4 strokes don't like to be mounted inverted (too wet around the plug) which causes running problems.
Can anyone tell me if this is true or not as I haven't had much experience with 4 strokes.

Thanks
