i finally got my new jato, my first nitro car YAY!!!!!! okay now the question is, the wire that connects on top of the glow plug, i tried to take it off, but it seems like its on their very good. is their a certain way to get it off or do you just pull? i didn't pull to hard, because i didn't wanna break it

also the low speed adjuster screw looks imposible to get too. any tips on how to reach that screw?
