I put a output of the portal gun to start my logic_scene, but it delays about 10 seconds before it starts and I didn't put a delay in the output. Is this put programmed in?

not sure if its hardwired in this case, but some entities have "default" values for their settings that if you DON"T change them, they won't show.
this could be the case, try PUTTING a delay of 0, or 0.1 something like that. and see if that clears it up

What entity are you using to trigger it?
