  If your Toro Compact Loader engine starts but doesn't keep running, here are a few things to check: * Restricted fuel tank vent: Loosen the cap. If it runs with the cap loosened, replace the cap. * Contaminated fuel system: Drain and flush the fuel system, then add fresh fuel. * Clogged fuel filter: Replace the fuel filter. * Air in the fuel: Bleed the nozzles and check for air leaks at fuel hose connections and fittings between the fuel tank and engine. * Improper fuel grade for cold weather: Drain the fuel system and replace the fuel filter. Add fresh fuel of proper grade for ambient temperature conditions. * Clogged spark arrestor screen: Clean or replace the spark arrestor screen. If the fuel pump is damaged, contact your Authorized Service Dealer.
