    Has anyone heard of problems with this engine relating to the EFI? I was told that there are a "shortage" of techs that work on the EFI for Kohlers and this could result in considerable delays, should it go down?

    The only bad thing I have heard is if the computer that controls the EFI gets wet it will most likely have to be replaced. I think Kohler may have done something about this by giving the computer a little more protection from the elements. This wouldn't be a problem on a new more with this engine now. I think this problem only existed when the engines first came out.

    Yes, these engines were a living nightmare for some owners and all of it EFI related.
    Some of the issues electronic, some of the issues fuel delivery.
    Some of it Kohler's fault...

    More of it the mower MFG's fault for lack of R&D.
    If you just bolt them on, what more can you expect?

    Be sure to ask about this for me, please. I spoke with the areas three larger Kohler dealers today. NONE of them recall servicing any EFI's at all. I think my next step is to talk to the sales people and see if this engine is actually selling on any of their units, regardless of mower manufacturer.

    Thanks for the info and keep it coming if you hear more.

    I also have 3 EFI's two 26hp(both over 1000 hours) and one 28hp (500 hours) all on Exmarks.No problems with the 28 put a fuel pump on one 26 and a regulator-rectifier on the other. I figured out what the problems were on both so I ordered parts and fixed them. I don't feel that the problems were the fault of the EFI I have had the same type of things go wrong with other engines it's just part of doing business. I will be getting another 28 hp EFI Exmark in Nov., love the power.

    I have a 26EFI in a 2000 Walker which makes it one of the first in the mass production year. I have over 1250 hrs on it. There was one warranty problem in the first 2 months, Bosch had a screen on the fuel pump that had a mesh that was too small. The result was fuses blowing as the pump strained for fuel. The pump was replaced under warranty and I have never looked back. It is sad to hear that you are having so many problems with that motor. I know that there can always be a bad apple in the bunch and I am not discounting the fact that you have problems. It sucks. I would write to Mr. Walker and explain the deal. The Walker company is very good to small business owners who have their equipment. They have a direct connection to the Kohler company and you may do better explaining to them. I know, it happened to me and my 97 Walker with a piece of junk 25HP Kohler. Good Luck.

    Yes-WALKER is very responsive. Your dealer should be your first stop!

    We run EFI units in our WALKERS and have never had a problem other than the fuel pump thing a few years ago.

    An important point that is often overlooked is that all EFI units should be warmed up for a few minutes in the mornings! The actual computer controlling does not start until the engine oil and exhaust temp reach a certain point. if you do a quick start and shut off on a regular basis you confuse the oxygen sensor, which is an easy fix. The dealer should have the program on his computer that hooks up to the engine and immediately diagnoses the problem!
