Good Day,
I have a 2006 Jinma 354 with a 485 engine. I live in Alberta and have always kept this tractor inside the garage in the winter. Its been sitting outside for 4months, its starts no problem, when I give it throttle it starts spewing black smoke and the engine sounds like it wants to die. If I use the hydraulics and lift the bucket, again no problem but if I put it down it spews black smoke and wants to die. Thought maybe there was an issue with the fuel, drained it, pulled off the sediment bowl and checked the two filters, the one inside the tank and the one at the top of the sediment bowl, blew out all the lines, hooked it all back up, bought new diesel, fueled her up and again same issue. Removed the air line thinking that there might be an obstruction, still can't throttle up. Removed the muffler, again, still can't throttle up but idles fine. I've cracked open the fuel line on each one the injectors and they all had pressure, but each time I did it the engine reved up a bit. Started her cold and checked the 4 cylinder walls and they all warmed up to the same temperature (checked it by touch). I tried manually increasing the rpm at the injector pump, had some success, but I had to increase the rpm very, very, very slowly to get it to full Throttle which almost took two minutes to do, but again when I applied some load it begin to die. Any suggestions? Thinking its either the timing or the fuel pump?
