The first thing I would do is pull the plug. See if it's wet and then check for spark using a good plug resting on engine?
Sometimes flywheel rusts. One small piece of rust touching the mag and no spark. Neighbor just had that problem.
Always check for spark first.
Second put a few drops of gas inside carb and see if you get fire.
Bet those steps weren't in manual, they are in Bubba's manual. LOL
