This is my first post here, so cut me some slack if it's been asked before. The DSR team has been posting quite a few videos lately of their warm ups. In all of them, a crew member tightens down what appears to be a slip collar on the mags BEFORE another guy puts the timing light on the engine, and almost as soon as the engine is running. After the timing light is removed, the first guy then tightens down another 2 collars. Now I can only imagine what would happen if the timing is off and someone tries to start a nitro motor, so can someone explain to me what exactly I'm seeing? Are the mags left loose at start up?
