There are many possible reasons for the hot start problem. Most likely is poor carburetor settings, which you won't be able to address yourself.
Check that all visible screws are tight, especially around the carburetor and air cleaner, replace the spark plug with a branded one (NGK, Champion, Bosch) with the gap set at .025" and throw away the fuel. Try it again on fresh fuel.
