When we try to start it the rope pulls real hard then snaps back so hard it scarey. It's a Toro self propelled and about 5 years old. Wasn't a problem until I hosed it off after mowing. Btw it does start.

so many answers...i had that problem until believe it or not i replaced the blade, perhaps it is loose or something.
my mower practically broke my arm or tore it outta it's socket a few times till i finally got to tinkering with it...
it worked a while then i replaced it
5 years is about the limit on push mowers anymore...sad but seems to be true.

Between the cord and the engine (among other parts) there is a one-way over-running clutch. When you pull the cord it engages with the engine allowing you to turn it. When the engine starts and begins rotating faster than the pully connected to the starting rope, it is supposed to immediately dis-engage! This is what is supposed to prevent the rope from being sucked back into the engine and your hand from getting ripped off! I suspect that your's is sticking in the "on" mode. It is probably got crud, or rust in it or needs lubrication. Because there are many variations in the design, I can't give specific repair instructions. One kind is located as part of the recoil start mechanism (when you remove the part of the engine coweling that has the starter handle, look underneath as you pull the rope, if you see a metal pawl move in and out this engages with the cup-like thing on the end of the crankshaft. If when looking under you only see an octagonal hole, the one-way clutch is located on the end of the crankshaft. It should have a square thing at the top; it should spin freely if you turn it opposite to normal engine rotation and engage when turning it the same way as engine rotation. These are the two types I commonly see. If you are not familiar with these kinds of repairs, I suggest you check your local library and see if they have any books on small engine repair.
Note: there is a tightly would spring that makes the cord rewind; careless dismantling of this part can let it suddenly fly out of the housing and cause injury!
There is one other way this cord-pulling phenomonon can happen. If the engine timing is so far off that the engine fires so far before TDC that it tries to rotate backwards! In this case the clutch won't dis-engage, because the engine is trying to go the wrong way! I don't think this is the case with your mower, as you say the engine does run once you get it started.

Dry it out- it'll work ok again. Maybe check/replace the spark plug.
Your owner's manual doesn't recommend spraying water all willy-nilly on everything, you should bag the topend first to prevent just the kinda problem you've got.

that sounds like it could be the fly wheel assembly or the start cord part. i would only reccomed you take it apart if you know what you are doing otherwise you could ruin the part and hurt yourself. if you take it to a small engine repair shop they will be able to fix it for next to nothing.

depending on what the rope is made of it may have shrunk when you hosed it off and so now it is too tight and you need to have it replaced or rewound.

Try lubricating the cord reel mechanism, not the cord though.
