If you're having trouble starting your Poulan Pro Lawn Mower, consider the following: * A dirty air filter can cause hard starting; clean or replace it. * A bad spark plug can also be the culprit; replace it. * If equipped, a weak or dead battery will cause hard starting; recharge or replace the battery. * A dirty fuel filter restricts fuel flow; replace the fuel filter. * Stale or dirty fuel can prevent the engine from starting easily; empty the fuel tank and refill it with fresh, clean gasoline. * Loose or damaged wiring can cause starting issues; check all wiring. * The carburetor may be out of adjustment; see 'To Adjust Carburetor' in the Service Adjustments section. * Engine valves might be out of adjustment; contact an authorized service center/department.
