    26 EFI is surging while idling. Didn't really notice while blades where engaged. Is the surging something I need to be concerned about. It may surge just a little while blades are engaged but not noticable. Is there a bigger problem in the future.

    Its probably something simple.
    Governor arm might have slipped a little
    Intake gasket might be leaking.
    Could be a partially clogged injector causing a lean condition.
    Did you sequence the ignition to check for ECU trouble codes?
    Turn switch on and off 3 times quickly and count the blinks on the dash light.

    I will have to check it out for codes, I'm acually looking at buying this mower. Really good shape 785 hours,has regular wear you would expect, has All Seasons Hi Lift. It just has the surging that has me concerned. Guy asking $6800.

    Should I be concerned with surging.

    Yes. I would be concerned.
    Walker mowers are labor intensive to get worked on.
    Most engine work requires pulling the engine.
    There are many things that can make an EFI engine surge, and a lot of them ain't cheap.
    I would try to get the guy that owns it to fix it. Before you buy his problem.

    surging is most likely dirt in fuel system....90% of the time....try and get codes then clear and run in open loop (no ecu) if it still surges clean ENTIRE fuel system and try again....good luck.

    Well.....I guess before I buy I'll take it and get it checked out. Possibly get suging resolved before money changes hands...any other suggestions are welcome
