My new hyper 7 pcr has just arrived and i haven't started it yet because i'm waiting for my friend to come round and help me. I got told that when you break in the engine you should put the piston at bottom dead center after running but i tried turning my flywheel but it wont go round so i'm scared that when i start it, i wont be able to put it BDC afterwards. Is the silver wheel by the engine, sticking out under the chassis, the flywheel? Does anyone have any ideas? Thanks...
