Toro 521 no tension on pull cord

Looking for some guidance here. After a good storm last night I spent two hours removing snow with my trusty Toro 521. This morning when I went to fire it up the pull cord had absolutely no tension when I pulled on it. It recoiled as normal. The electric starter sounded like it was spinning freely. Where do I start? I am not an engine expert but I can get my hands dirty. Thanks,

Remove the spark plug. Put your thumb over the hole.
You may need help now. Pull over the engine (may need some one to do that for you if you can't reach & hold your thumb).
If it does not push your thumb off the hole, you have no compression. Could be a stuck valve or worse.
