i cant get four wheeler start but it only crank

 

You need to confirm it has the following:
1) Spark - pull out the plug, ground to frame or wrench and verify you have spark
2) Fuel - if you have spark but not sure if plug is getting fuel (dry), then spray 2-3 seconds of starter fluid directly into plug hole, replace plug & crank. If it starts then dies it's not getting fuel
3) Compression - if you know it has spark and doesn't start on starter fluid you need to verify your compression...if too low it will not start...


Start with these first...
