Could be the valve in the carby. Had a similar problem with my Victa. Have a look on the internet for briggs and Stratton engine carby service. It was really helpful. Your carby may be different but the info I found was very helpful and explains how the power valve operates and what to do to prevent surges and power loss.

Have you ever oiled all the little working parts on your mower? The adjusters also get dry and they rust up or just get dirty. You can try to oil all the areas that move on the height adjusters and see what happens.

it has an electromagnetic clutch switch on it,that is more than likely bad. Try this,pull the pto switch out and start the engine,then disconnect the 2 wires coming from the switch and just tap them together and see if they will come on. If they do then you need to replace that switch.

Usually it is easiest to pull the bolt, washers, and spacer that hols on the idler pulley. The only items are belt guides if so equipped.

check to make sure your safty switch is not engaging causing no spark other than that your coil would be bad but they hardly ever go bad i think your problem is with the safty switch

Could be several things. Starter sol hooked up wrong, key switch bad... well ok thats pretty much it, check those things then see what happens.

There could be a whole bunch of things to cause this, from a badly worn engine to just a valve stuck open, a dealer could do a leakdown test on the engine and give a more definate reason for the problem, or you could remove the cylinder head ( side valve engine ) and check the valves are opening whilst turning the engine.

sounds like a float style carb and your dumping fuel into the engine when you tip it is your fuel line long enough to add a shut off valve?

The gap should be about .010 (Ten Thousandths of an inch), but truthfully, the way I set it is to loosen the coil bolts and place a shiny business card in between the coil and flywheel. Tighten the coil up snug against the business card and then remove it. This should set the gap close enough to the correct setting for you; done. Hope this helps and best of luck to you.

I have the same machine, [pull plug wire for safety] tip machine on it's side, next remove blade, now remove all the plastic shields that are above blade right to the deck bottom. You wont believe the grass build up around blade shaft. On this machine as you select your speed the pulley travels on shaft, but with the grass build up the pulley can't move. I've done mine twice now in the last 4 years. You'll need around 3 hours, good luck it's not that bad.

This sounds like fuel starvation. This is usually caused by debris in the fuel float bowl or a dirty fuel filter (if used). Remove the fuel float bowl and clean out the debris. With the bowl removed use a spray paint can lid as a catch pan and check fuel flow. With the float down it should fill the spray paint can lid in about 10 seconds. If you do not have this much fuel flow you need to inspect the tank outlet port, fuel lines and filter (if used).
The 20029 & 20099 models came with either a Briggs & Stratton or Kohler Courage XT7 engine. I need to know what engine you have to provide any diagrams on what to check or clean. A n engine model number would be even better. (Please!) Since the post is labeled with the 20099 model I will cite that as a reference. This SERVICE manual should help you with repairs:

See page 27 of the manual for fuel filter location. (Optional if used) AN exploded view is on page 31.

If you have the primer bulb model see page 24 and note the ondition of the primer bulb and primer bulb hose. Any hole in the primer bulb or cracks in the primer bulb hose can also cause this symptom.

If you have the Briggs and Stratton engine (Model 20029) I need the engine number to get you the correct manual data please. Otherwise...this should help you resolve the problem.

No No No No!!! If your mower is definitely a 4 stroke then do NOT put 2 cycle engine oil in it (and I hope they didn't either). Drain out whatever's in there completely and put standard 30 wt. oil in there. Not 10W30, but straight 30 weight. Use synthetic even if you want longer engine life.
