First thing to check would be the base governor setting.This should be done by someone with small engine expertise.Can be fatal to engine and do bodily harm if not done right.Other things to check would be air leaks where carb manifold attaches to heads.Remove air cleaner assembly to gain access to carb linkage and manifold.You will need a can of carb cleaner to perform this check.Start engine and hold throttle at just above idle speed and carefully spray area where manifold attaches to head,do this on both ends of manfold and at carb base,area where carb mounts to manifold,if leak is present the engine will either die or their will be a change in rpm,s.If no leaks are found in these areas have carb cleaned,it is very likely there is dirt in the carb.You can do the same as above,start engine and hold throttle just above idle and spray carb cleaner into carb,engine will try to stall when doing this,only spray carb cleaner in carb while engine is running.If this doesn't help have carb cleaned and adjusted.Info from small engine tech with forty plus years experience.

Mtd yardworks walk behind starts then idles down shuts off after 20 seconds whats wromg

Usually when a mower dies, it is a fuel delivery problem. Have you changed the filter? Is the gas fresh. Also has the air filter and spark plug been changed recently? the Carburetor may need to cleaned. Take the air cleaner off and spray some carb cleaner in the throat of the carb. Also, take about 1/3 bottle of carb/fuel system cleaner and add it to the gas in the tank.. For the new mower engines, there is no fine-tune adjustments on the carburetor. Also clean the exterior of the carb with carb spray.

thats what it sounds like, a bad or clogged up fuel filter. if it bogs down when giving it gas, or going up a hill. its probably the fuel filter not letting enough fuel to engine. that is why it stalls at a stop. if this helps but not fully. check or clean idle air control motor. this is what maintains proper idle of vehicle. have a good day !!

Mower starts and stops with in a few seconds

Ok your not getting fuel into the carburetor it sounds. This could be either your carb.needs cleaned or your low idle screw on the carb. needs adjusted. The idle screw is located directly underneath the air filter. Remove filter and turn clockwise all the way and then counter-clockwise 2 1/4 turns, then test. Adjust until it sounds about right.
