Hi everyone. My friend has this neat little tractor. He's having a problem with getting it running. He was hauling wood Nd stopped for the day and it wouldn't start the next day. He towed it into the garage to warm it up. But still no luck. It cranks fine. The fuel system has been rebuilt recently. There is no restriction in the intake or exhaust. The glow plugs work. He shot some WD-40 in the intake but it still didn't fire. He just pulled the valve cover and found all the valves lose. He's now looking for the valve lash spec. It has a 2 cyl
