Hitachi EX270 LC, Loss of power/stalling

dimanche 27 avril 2014

Fired the ole girl up for season, Inspected and warmed up. Worker great for about 5 minutes.. When touch travel levers it loses power and stalls. Replaced fuel filter with no help. Is a real pain to get restarted and thought was pulling air into fuel supply. Dealer suggested lift pump or air leak. Drained fuel and removed all fittings, hoses, lift pump, and water trap. Replaced lift pump and primer, double clamped hoses too no avail.

Once starts stalling from lever movement it struggles to recover and generally will stall out even if barely move a travel lever.It does not sound like a load is pulling down, more like fuel is being derated. No black smoke from load.

Sugestions anyone with experience on these vintage pieces??
