Hello everyone, I'm trying to figure out my lawn mower, it's a Ford yt18h with the Kohler magnum 18hp engine. I have used this tractor for about a year and have never had any issues whatsoever with this machine, until last weekend. I got brave and tried to mow the road side of my ditch and got it stuck at quite an incline. I pulled it out, and it ran great the rest of that evening. I went to mow the lawn this past Sunday after it had say for a week, and it will not start. I replaced the fuel filter, as it had a crack in it and i replaced the spark plugs because they looked awful. I took the carb off and cleaned it but it was very clean to begin with. I found that there was no fuel getting to the bowl, but the filter was getting fuel. I applied vacuum to the line at the bowl to suck fuel down to the bowl, reattached the line and hit it with starting fluid and it ran. I mowed most of my lawn but shut it off before i finished. I came back out and it is dead yet again, same issue. Any ideas?
