    No, it is one of their Critical Power engines, which means the 27 HP rating is actual/true, whereas before it was 31 under the old system. Under the old system of J1940, they only had to come withing 15% of the labeled hp to be rated at that number, or in other words, they only had to turn up a minimum of 85% of the label listed HP.

    I see, thanks Ridin. Also I think the 36 BB which comes on Ferris 3100, was also rated like this. So its more likely a 31hp.

    I think the power has reached it's max tbh. The way the efi works is different than the carb engines. Sudden changes seem to drop the rpm on the efi then it climbs back up. It seems to like a steady pace on steep hills for example. Try and increase speed while in the middle of a steep climb and the rpms will drop. Keep the rpm steady and it does not drop.

    Same experience PSC.

    Ad in bigger pumps and 22 less cc's and you had my situation with the SuperZ.

    Now with the Big Block, if I try to increase speed on a hill, it just pulls a wheel stand and goes.

    EFI does everything in its power to keep the rpms from falling, and recovers much more quickly under load. When you feel or hear the engine drop well below its needed operating rpms, it is saying, I don't have enough hp to fulfill this needed power requirement at this particular time.

    I cut a couple hills that are so steep the nose gets extremely light and it hasn't had a problem with them. It is plenty of power for the 460 but it wouldn't handle a bagger that's for sure. I am tickled with the fuel usage.

    PSC, what was that the HO brought out and carried off on the moped? A Gas can? It looked like it anyway. Too funny.:laugh:

    Looks like a red bag with maybe lunch in it? I am starting to wonder if that guy lost his license or something. How can you go from a new lexus IS250 to a moped? He is a nice guy and generally leaves me alone which is how I like it. One year he decided to have tru green treat it and I could have choked his little oriental azz. All they did was pump fertilizer down real heavy all year and everything including the weeds grew like wild fire. :hammerhead:

    I was laughing watching the guy walking around with that helmet on. He reminded me of that old Flinstone cartoon with the little martian guy in the helmet who could only be seen by Fred.

    Maybe it was the camera lens or angle, but that looks like a decent sized yard?
