i cant get fire, ive put in a new spark plug and sparkplug holder. anything else can go wrong with it to stop the fire?

 

take your spark plug out and connect the wires to it and push the start button if you don see a spark then there is most likely something wrong withyour wires.

 

make sure the plug is grounded or it wont spark

 

Battery dead or disconnected? Kill switch on?

 

does it even try to start. If not then i probably know what your problem is. There is a wire that came disconected. The wire that it most likely is is under the quad near the brake. If you want to see if this is your problem try pull starting it and then see if it starts.
