The couple of "starts only if snort of ether" lawn mowers I've serviced, the problem has been leaky or missing gasket between the carb and the side of the engine body.
Please install said gasket if missing. If gasket is there, don your surgical scrubs and disposable gloves and seal the gasket on both sides with Permatex IIb non hardening gasket sealer. The stuff takes days to wear off your hands. (Alcohol drygas removes the stuff.)

Ive completely disassembled the carburetor and soaked it overnight in solvent then sprayed it aggressively with carburetor cleaner. All parts are clean and all holes appear to be clear including the jet. But it still wont run! Ive got fresh fuel and it is getting to the carb because I pull the bowl off and there gas in it. Any help would be highly appreciated!! Thanks!
