I just bought a brand new (supposed) X12 Rody from someone who bought it at the end of the last year season without using it at all. So I got it brand new in the box.
There is one thing weird though. I would appreciate if you can help me on this.
I thought that the compression was pretty tough, since it was very difficult to turn the fly wheel with my finger.
So this morning I put the car on an OFNA starter box, and the box wasn't strong enough to turn the flywheel.
So after looking around I remove the sparkplug to be able to turn the flywheel freely. I was amazed to see that the same friction occurs even with no sparkplug.
So briefly, is it normal that a piston move freely in a sleeve but has a lot of friction when it come at the top of the sleeve? (even with the sparkplug out).
If yes, I wonder how I will start that engine since my box is not even able to turn it without the plug
