Are you sure there is no water in gas tank, are you sure you get spark with new plug? component cleaned include carb and its components inside and out? If it turns over and does not stay running maybe first bet, you have water in the gas, second there is some kind of blockage within the carb probably so small you would not believe that it could be a problem.
If you disconnect the hose from the carb and empty some gas into a clear jar of some sort you can see if you have water in the gas. You will see two levels in the jar if contaminated, a yellowish gasoline level and a clear bubbly level which would be be water. Gas separated by something else means your mower will not start! Should be all yellowish in color.

158cc yard machine, starts then dies.

Your fuel tank and carb need to be removed, both cleaned and replace pump diaphragm between carb and tank. If you want to do it yourself, let me know and I;ll tell you how. Not a difficult job. Dwain
