Welcome to the forum!As to your problem,there are a few things to check.First,check the fuse on the red/white wire.Next,check for spark,at the plugs.If there's no spark,check the coil kill wire(unhook it,crank it over,to see if it gets spark at the plugs.If there's still no spark,recheck the air gap,at the magneto.It should be 0.012/0.014).This is all presuming,of course that the engine rolls over,without starting.IF it's a case of the engine doesn't roll over,track the harness,and check the safety switches,by jumpering them.If you need a wiring diagram,Go to
www.partstree.com ,and where it says make,type in troybilt.where it says model,type in 13060.It will show a list,among them,is a wiring diagram. Good luck,and if you still need help,let us know.
