Need to check fuel flow into the carb. Remove the fuel line from the carb and observe the flow of fuel coming out of the fuel line. If not a full stream then there is an obstruction preventing fuel flow. and could cause the issue that you have because it is burning fuel faster than it can refill the carb.
also keep in mind that MTD likes to hide a screen in the inlet fuel pipe that cannot be directly accessed and depending on material lodged in the screen cannot be blown out with compressed are. So may need to look hard down into the fuel inlet with a magnefying glass and check for debris, and may need both compressed air and carb cleaner to get the stuff out of the screen. That screen plugging will also cause your issues.

AT the carb right?
yes
all are there.
What have you done to fix it exactly?
Fill the tank completely. Drain into a glass jar. See if the tank empties fully with a purpose.
How did you check spark?

So it runs for 10 seconds and dies. You have the proper recipe for THAT 10 seconds. After that you are missing something. What do you think it might be?
yes
I am at a loss as to what to do. If it was timing, it wouldn't run as it runs smooth for 10 sec. Plenty of gas flow and good spark
