POULAN PRO - 2014, 38" RIDING MOWER, PB145G38, ENGINE B&S MODEL NO 31R607-0005-G1 (585822301): Will not start at any position on the throttle. 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. Did annual clean and adjust in January, change oil, new plug, exterior cleaned, tank/lines/carb flushed, new fuel filter, new air filter, adjusted coil. Have been mowing since February. Any suggestions?
POULAN PRO, starts only when air intake is blocked.

Check your fuel pump output to the carb. Pump can be bad and by blocking the air intake you are using engine vacuum to suck fuel in, and the pump is doing nothing(even though it works on vacuum pulses from engine...when it's working!)
Good luck!
