Will start if I cover the air intake with my fingers, runs with the air that slips past my fingers, if I spread my fingers any it dies, does not smoke or smell rich. outside air temp 80, humidity 28%, half tank of gas. Had trouble last week, started on full choke after warm up ran at the normal throttle level.

Carburetor needs cleaned. Don't buy a cheapie Chinese replacement from Amazon or eBay; just clean (or have it cleaned).
