I bought this machine last year to do some work around my house. It's got 2900 hours on it. Ran like a champ when I got it. I've only put about 75 hours on it in over a year. I loaned it to a friend and when it came back it was running rough with a loss of power at mid to high RPM. It starts right up quickly and idles perfectly but when I increase the throttle, it gets rough and loses power. I'm trying to start troubleshooting this because I need to use the machine for some drainage work in the next month. This machine was the Isuzu 2.2l 4LE2 motor. I have ordered new air, fuel and oil filters and will be installing them next week. I'm hoping it's just something simple like a clogged air filter but we'll see.... If anyone has any input on how to diagnose this issue, I'd be very grateful.
