Could water in the fuel cause hard starting even when it is 50 degrees out?? I have some condensation in fuel cap whenever I open it. The tractor sat for 6-7 years before I got it. It runs a little rough for the first 5-10 minutes and then smooths out nicely. Seems a little low on power also. Could this be the injectors?? Tired motor?? Or could a little moisture cause this?? Any help would be appreciated. Thanks | ||

Moisture in a diesel fuel system is bad. It will rust the internals of both the pump and injectors. One sign of bad injectors is wet-stacking, which is fuel coming out of the exhaust. Also, smell the engine oil for diesel. If the injectors are bad, fuel won't burn completly and gets into the crank case. I would eliminate the chance of a water problem first. Drain the tank and change the filters. Water isn't going to help things at all. After that, I would do a compression test. Do your injectors go in below the exhaust manifold or above it? | ||

The tractor is a 1965 model. It has a 283 Waukasha engine in it. ( Has energy cells ) There is no escessive fuel coming out of exhaust. The oil looks good too. No fuel getting in it. I changed both filters again, drained tank, and filled with fresh #1 fuel for the winter and put some injector cleaner in it. Will be a few days before I will get time to run it again and see if it gets any better. Thanks for the reply. | ||

I got a chance to run it for a little while tonight, just some light loader work. I seems to start somwhat better. The power seems better also, but it does seem to smoke a little whiteish gray. Would the #1 fuel make this? Someone said to feel the energy cells to see if one was hotter than others, I did that and they all felt equally warm. What is a good compression number for this tractor? Thank you Chris for all your help so far. | ||

Also, what does anyone think about the idea of running turpentine or laquar thinner through the injector pump to clean it out?? | ||

diesel fuel conditioner and a good set of plows will go a long way! | ||

You might want to take the energy cells out and clean them. If the orifice is plugged, it will definitely cause hard starting and poor cold performance. As to compression, I don't have a book here, so I can't give you an exact number, but the readings should all be pretty close to each other. Is your water temperature coming up to normal? A diesel that isn't getting warmed up will tend to have smokey exhaust. I would get some diesel fuel injector cleaner, put it in the tank and take that tractor out and work it for a few hours. Also, a good starter and batteries are a must for starting a diesel. It doesn't take much loss in cranking speed to make a big difference in starting ability. |
