Check for spark by removing plug and leaving spark plug flex, pull cord, if no spark: stir to check ignition below. If spark: remove air filter and run to see if it still dies, filter should miss light, but this is probably not problem. My guess its starved for fuel or vapor locked: run at 50% power to see if prob go away. If not: need a carb do again and the intake manifold stamp replaced.
No spark: coil bad or ign chain bad.
Weak spark: remove flywheel and use scrubber wad to remove any rust from magneto magnets.

Answers:    Check the atmosphere filter. Sometimes they will fill up near gunk and prevent air flow. If it is slippery and dirty replace it. Also your gas may be old replace that too. The spark plug human being on securly is not enough. You will stipulation to remove it, let it hang up freely, and give the verbs a pull; did it spark bright? Might requirement to replace that too. You also may have a bleak fuel and additive mixture. replace the fuel and mix beside the correct amount of additive. And BTW you do not have need of to be an expert for any of this stuff. You can do it.
