Must have tools?

Hello guys, its been a long time since I have been on this forum but I was hoping I could get some information from you guys. I'm interested in getting into small engine repair as a sort of hobby, but I own absolutely no tools. I have a bit of spare money and I was hoping I could get some general information on what the "must haves" are that would allow you to pretty much do any job?

Thanks.
