I've owned this tractor for several years, and it always ran well. About 5 months ago, I would start the tractor, work for a while, and then all of a sudden, the engine would race up to 2500 RPM, sputter just a bit, and die. I couldn't get it started again until the next day. I'd prime it with the lift pump lever, bleed it, etc... and it would start. It's gotten worse over time. I've replaced the lift pump, filters, fuel lines, have very little sediment in the bowl, am getting fuel to the injector pump. Read on the Forum that the Thermometer might have something to do with uneven heating, so I replaced that. When it runs, it purrs along. Then, sometimes it's 5 minutes, sometimes 35 minutes, sometimes just idling, sometimes at full (540 PTO RPM) throttle, the engine races, and dies. When this happens, it seems I can't get it started again until it cools/overnight. Re-prime, do it all again. CAV injector pump... can they "slowly" go out? I know I'm getting fuel, and can't find a leak anywhere, no bubbles, no air in the filter cups, nothing. Is it just an old (looks original) injector pump that is slowly going out, or ??? IT'S DRIVING ME CRAZY! Help is appreciated. Thanks, Ross
