Been having an issue with my zero turn, its a Ferris with the Kawasaki FX1000V with a carb. I only run ethanol free 89 or 91 octane in it. Air filter is clean and it has fresh spark plugs in it.
When I drug it out of hiberation a couple weeks ago, it was hard to start, but I figured that was just from sitting for a few months and having to suck fuel through the lines. It was never "fast" to crank, but 10-20 seconds of turning over after a long hiatus would get it going. So get it going and I'd been cutting for about a half hour, and it started running rough like it was about to die. I pulled the choke and it smoothed out and kept running for another minute or so then died. Wouldn't recrank until I let it cool off a couple hours. Found a crack in the suction line that goes from the block to the fuel pump, replaced that piece, and every other fuel and vent line while I was at it. Next few times I cut grass, it started faster and easier than it ever has, and ran without issue. Then this past weekend, I go to crank it, and it hits almost instantly, but then dies, and then is a pain in the ass to start. Finally use some starting fluid and it cranks up, and after running on starting fluid a couple seconds, it starts running on gas. Fine, I go about my business, get 20-30 minutes into cutting and it starts running rough again after it gets good and hot. I choke it, make it over to the garage, and cut it off, let it cool down for a few hours. Go back to it, dang thing won't start without starting fluid again. Get to cutting, make it 15-20 minutes, and it cuts off again. Sprayed cool water on the ignition coil, tried to crank, still nothing. Seems like a fuel supply issue since it has enough spark to easily crank/run on starting fluid. Do the plastic fuel pumps heat soak and not pump good? Anybody got any suggestions on what to check next. I cleaned the carb after the first incident, but it looked really good with no gumming and just the faintest green/yellow residue on the bottom of the bowl.
