Here are some picture to help you out , pay close attention to the third one , you need to shim up the lid with a 3/4" tube so the lid comes up , this is needed so the starter wheel rotates before any part will hit the wheel , what happens alot on the chrome top + 8ight is that it will hit something before the wheel in teh box can build some momentum.

1) set your pins to the pictures
2) shim the lid - IMPORTANT !! i found this to make the box work 10x better
3) chamfer the wheel a bit ( i use a box cutter and push down on the box to make the wheel rotate don't cut INTO the rotation hold the knife on a angle so it will actuallly RUB the wheel instead of straight cutting it, do this outside cause it will smoke big time...but is the easiest way and best way to chamfer a wheel)
4) you may or may not need to chamfer the edges of the chassis , it doesn't need much , but because the wheel is larger you may have to to keep the wheel from hitting the edge of the chassis)

my box i just put the 8ight on it and push the ignitor on it , and that's it , it will start every time...
