Assuming it is a B+S engine, if it starts fine and runs rough and smokey as it gets warm and will not get enough speed, the problem is with the Diaphragm between the carb and fuel tank, it costs about £3 and is easy to fit if you have a 10mm and 13mm spanners and a cross heded screwdriver, ver annoying but relatively cheap and simple fix. Max.
Assuming you have a fairly clean air filter and a good spark plug, my first guess would be the gas. Make sure it's fresh. Also check the gas tank for dirt and/or water, especially if it hasn't been used for a while, and clean and/or drain the tank if you need to. If you've done all this, maybe the carb. needs adjusting.
Water in tank and bowl.....dump ALL GAS from tank and line....then gently loosen bowl screw (1/2 in. small socket) until all gas drains from bowl....gently tighten bowl screw back snugly....put new gas in....give it 2 min. to fill up bowl...prime it 5-6 times ...crank it up....p.s. might need to help it out a little with some starter fluid sprayed into carb.

Sounds like the automatic choke to me. When it acts up next time, remove the air filter, and observe the butterfly valve on the carb. Hold it open with a screwdriver, and see if it starts and runs. I have found that wireing the thing wide open solved my Toro problems. The mower is still under factory warrenty however, so you can always take it back! Hope this helps my friend!
This happens often. Sometimes your mower will start and run again and sometimes it won't. When it doesn't run it's because your timing is off, caused by a dented or sheared key. To replace remove top cover to engine, and any other side attachments, this should expose the flywheel. Remove the top bolt and look between flywheel and top of crankshaft, you will see a small square notch. This is where the shear key is placed. Remove the flywheel and replace the shear key. Replace all parts in reverse order and you should be mowing again. GOOD LUCK.
If you are sure the oil level is correct then it sounds like it's about to die, unfortunately. A pine cone shouldn't cause any damage, but a large branch may do so. Was it smoking before you shut it down? The vibration could be caused from a bent blade. It could also be caused from a part breaking in the motor. I wish I could have given you better news!
Sounds like you will need to clean your carburetor.
Sometimes you can get by with priming it a few times, and letting it run a few times like that and it will flush the gunk out of the jets, but most of the time you will need to rebuild the carburetor. If the mower is over a couple years old, then I also recommend that you buy and install a new carburetor repair kit, because the diaphragm will get hard and that will cause it to be hard to crank. When you clean your carburetor and remove the jet screws, count the number of turns it takes to seat the jets from their original position. That way when you go to put the jets back in, you know how many turns they were in/out. Please rate me, Thanks Good Luck, I hope this helped
Check the governor spring to see if it is streched out or the bracket it attaches to is bent,this can cause the problem. Also the carb may need cleaned and rebuilt,if it contains a diaphram gasket it could be bad causing it to die.
it would be a lot easier if you take the cover off the top of lawn mower. find the carb, it usually sits near gas tank, there should be a screw sticking out of it. tighten until it runs normal. also adjust the air intake/ throttle arm on carb
