The black smoke tells me that the engine is flooding and getting too much gas.This is caused by either a choke that is not coming off, a very dirty air filter or a carburetor that is flooding and needs to be cleaned and rebuilt with a niew carburetor repair kit.There is a possiblity that there could be other issues as well such as valve etc. but most of the time the three things I mentioned are the problems.
