Bent shaft is rightThe fix is easy . Replace everything underneath the gas cap. Need a new engine my friend might as well buy another mower. weigh the cost of the repair,new engine or new mower go with the best deal. There is now that I think of it a key on the shaft somewhere that might have broke now that's not a bad fix. Not sure if they still put them on there. Key or shear pin all the same. That might be worth checking out. Maybe someone else in this forum will know. Best of luck

The computer I'm on doesn't have any speakers, so I can't listen, but I can offer some ideas anyway.
First, never run a lawn mower without a blade attached, the engine will overspeed and that can cause serious internal damage.
If the mower is vibrating a lot when you attach a straight blade, then you can be quite sure the crankshaft is bent and the motor is trash.
If the motor is not vibrating more than usual, but still sounds rough you quite likely sheared the flywheel key and have thrown the timing off. You will need to take it to a small engine shop and have the flywheel removed and the flywheel key replaced. That will solve the timing problem. Good luck.

It's hard to tell from the video sound, but part of the problem may be that there is no blade installed. The mass of the rotating blade adds to the flywheel effect to smooth out the cycle of the engine, as well as adding the load of the drag. If there is abnormal vibration, I would suspect the bent crankshaft, and a knocking/ slapping sound as connecting rod/ crankshaft damage.

Check the shear-pin where the blade attaches to the crank. If it is intact, you may have seriously bent the crank. If it broke, it
can be assumed that the blade has to be replaced but the
engine is O.K.

The engine is probably toast. Sounds like a bent shaft so major cost and labor.

When it warms up and splutters, is it puffing black smoke? That's an excessively rich mixture, could be the choke is stuck on or the air filter needs cleaning. The reason it goes again after a while is that it has cooled down and can handle the excess for a bit until it warms up again.

Probably a bent crankshaft or bent rod. Take to the shop and see what they think.
