125m wiring problem Please help

[WannaRace400ex]

OK i have been asking all these qustions on how to split the cases to replace a broken side that is all done know. I'm putting a 125m motor on a 110 I have the motor mounted and there is no spark.
Do I have to have the battery to start it?
Does anyone have a wiring diagram they can email me?
ANY HELP WOULD BE GREAT
Thanks Eric

Also The timing may have got off, does this have any effect on spark?
