The fact that it is cranking is a good start. Air, fuel, and fire is a different story.
It needs to have the right amount of air/fuel ratio, and fire at the right time to be able to start and run. It also needs to have good compression.
Spray a 2-second shot of carb cleaner into the carb(WOT) before cranking, then see if it will fire up.

thanks 89 I will try that in the morning I did try some starting fluid but not at wot it's crazy kinda like out of time it wants to fire but wont run

If it was running before, and you changed nothing, it is probably something simple.

tried the carb cleaner with no luck 89 do you know what compression should be I am going to get a tester today. also I am getting smoke out of the carb air intake after trying to start

You want at least 100 minimum, but it should start and run decent with 90.
Try a new plug.

hey 89 you would not believe what was wrong with my buggy
I pulled the muffler off and it fired right up after inspection of the muffler the tail pipe was packed full of mud so some little critter played one heck of a joke on me I cleaned it out and it rung fine
