Red Bull 42206 Chapter 2 engine pistons won’t move. What am I doing wrong? My

I’m in chapter 2 of the Redbull F1 (42206) and I’m trying to attach the engine to the gearbox (I think, the chapter 1 piece) and the pistons aren’t moving freely. And the book says it should. And before you say I should’ve googled harder, I tried. TIA! submitted by /u/someredditor12345 [link] [comments]
