Put up with it too much last year. It does not want to move forward. At first. Backwards is a bit better. Until it warms up. Then it does much better. But still not good enough. I have to get a running start to get it up the hills to cut the grass. And there are quite a few hilly challenges here. I moved it to the barn today and will start on it next week. I suspect something in the pump. And there's an oil leak. Oh yeah....I don't know how it's getting in there, but the oil is always getting water in it. I fabbed up new filler tube and cap, as the old one would not seal any more. The 'O' ring at the lower end of the fill tube would just not seal. Lots of work to do on my wife's Baby.
