Hi Guys, First, I hope everyone had a good Thanksgiving! We had a big turkey lunch, and then I spent all afternoon on my Raider 10 moving 5 yards of hardwood mulch. A little background on the tractor, then my question. The 10 hp Tecumseh was replaced by a 14hp Tecumseh (HH140). The engine was rebuilt when it was installed several years ago and has had little use since. The engine runs great, but starting is a bit of an issue. The engine fires up normally when cold. Pull the choke, turn the key and it comes to life. What is odd is that even when fully warmed up, I have to choke the engine to get it to fire. I had this problem when I first acquired the tractor this Summer, I went through the carb and cleaned it out, and rebuilt the fuel pump. I adjusted the carb, replaced all the fuel lines and put on a new fuel filter. I only run non-ethanol gas. I was taught you never choke a warm engine, but I believe I could spin the warm engine until the battery died without it firing. But pull the choke, and it fires right up. What is going on? The carb is the original Walbro LMH dated 4-1-74. Is it time for a new carb? If so, which one? I see many carbs on EBay, but don’t know if they will work on my Techy without modification. Most say they fit Kohler. If this were a V8 with a Holley, I would be a lot more comfortable... Any advice greatly appreciated! Thanks! Danny
