3.3 nitro compression?

Motoman · Sep 8, 2013

I can turn my crank by hand, with the spark plug out, very easily, should it be that easy?

Yes there is no compression to make it "hard" to turn.

I thought there would be a little restriction or pinch when the piston reaches TDC, as I recall.

Maybe some, but most of my motors are just like that. And they are pretty sloppy they all run fine and work.

Does it turn with the plug in? If not you're good to go.
