Whhy doent my sortsman want to start ??

Ok 4 things could be the problem,
check to see if you have spark. if you have spark then spray some starting fluid into the carburetor or air box. if it does not start then check the compression, if the compression is good, and you have spark then check the camshaft. these have been known to eat the exhaust lobe of the camshaft right off. that is where i would start.
