I have a Kubota Z482. It was brand new when I installed it 2.5 years ago, and it has maybe 40 hours on it at this point.
goes from the tank to a primer ball to an inline filter to a bowl filter and then to the injection pump.
It's self-priming and always start right away. Purrs like a kitten.
However, unless I let it run for a few minutes, it dies under load. Once it's warm, it does fine.
For example, if I turn it on cold and start backing out of the slip, if it doesn't die when I first hit reverse, it will die when I click back into forward.
Also, if I turn it on cold after sailing and start motoring in, it will run ok for a couple minutes and then start sputtering. If I kick it into neutral, rev it up for a second, then put it back in gear
, it's fine and will run normal all the way home.
I just changed the filters, but that didn't seem to change the problem at all. Any other ideas?
Like I said, if I let it warm up a couple minutes it's fine, but I know that's not the way it's actually supposed to work.
