I'm new to this forum and I've recently acquired a JD 285 lawn tractor. It has the Kawasaki engine liquid cooled. Here is my issue. When I start it it runs for 30 seconds and quits. I put a new filter on it and new lines from filter to pump. No difference. The gas is fresh (non ethanol) just purchased yesterday. Old fuel had been drained or evaporated away as the tank was dry when I got it. This unit has sat outside for the last year and a half, in the elements of western NY, rain, snow, sun. Here is one thing I did notice, I un-hooked the fuel line to drain the new fuel after it had no effect on the mower running better. The fuel should have drained out of the line back in to the can. It did not even trickle out of the line. Is there a screen or filter in the tank? Any help would be appreciated. I have seen this issue on other searches on the web but never any conclusions for getting it resolved. Mower would run for a minute or so then quit.
