Check the carb. Hell, replace the carb it’s a fairly easy swaptronic diagnosis.

Have you run it long enough to clear out any possibly pooled fuel or oil before you condemn the carb? I've got a float bowl style 2-Troke (2-Tycle?) snowblower that needs a solid minute to clear out pooled oil rich/gas evaporated residue after sitting. After that starts runs normal.

I have ran it,but have to feather throttle to keep running.attempted adjusting carb settings. But it is quick to die.set them to ~factory settings.
