Loose injector adjustment

[Lonestar10]

loose maybe not get the full shot of fuel, a tiny bit of timing change, if its not touching at all with no preload maybe the taping of the rocker onto the injector could cause cracking depending on the types of metal for injector rod and rocker arm, and possibly if the rod and rocker seperate to far the rod might turn and come out from under rocker.. just some things i can think of depending on how "loose" you guys are talking i havent seen the vids.
