maybe try letting the motor get warmed up. i`ve had jd tractors that slobbered after starting but then would clear up after a good warmup. this happened during cold chilly wx.
so, for 20 hours it has been running bad? my experience with a 5225. probably different engine, but i had a difficult time changing the fuel filter one time and it is a hard thing to do even in january. i would make sure that the filter is in correctly and the spring and gaskets in the right...
I have the 5225 version. maybe different engine 5cyl. little over 1000hrs. only problem is that it shuts off random but if i react fast enough, i push the clutch and turn key off on real quick. does not happen often.
I would like a new floor for my one car garage. but,,,i worry about using jack hammers and the foundation of the house(an over 100year old house with block foundation). Are there issues doing this?
