My Series 1 D17 loses all power, and sometimes dies if heading uphill. Is this a float problem? Gas tank is full. If I stop and wait a minute, it will line and and run again, and if I point its nose downhill, it will run fine. It has a rebuilt carb on from Steve at B&B. Below is the tag on the carb.  |

Any chance there might be something floating in your fuel tank that plugs the fuel line when you're heading uphill, then floats away when going downhill? ------------- WC, CA, D14, WD45 |

Possible. I coated the interior many years back, so a hunk of that could have flaked off. I will look. Also, looking back through my records, I am not sure where the carb came from, it is about 10 or 12 years old now. - Roscoe

| open up the drain on the carb and make sure a steady flow of gas occurs. If so, then possibly a float adjustment issue. If not, plugged strainer or fuel blockage. |

My D-10 would run good, first part of the morning, while on a caravan. Then after a break it did not run well, I would have to use the choke. I found that I had set the float wrong, it was too lean. When the gas was cool the D-10 ran fine, but when the day got rather hot, and the carb had heat soaked, is when I had troubles. After readjusting the float, it runs fine.

Did you add an inline fuel filter? The common ones used in cars are not suitable for gravity systems, too much pressure drop. And when the tractor is going up hill with the carburetor mid or forward on the engine and the outlet of the tank at the rear the gravity head gets small. Then the line could be nearly filled with varnish. Gerald J. |

I vote the float needs adjustment to allow more gas into bowl. ------------- 1957 WD45 dad's first AC 1968 one-seventy 1956 F40 Ferguson |

my wd would shut off when the govenor would kick it. the previosos owner put a nail were for a cotter pin were the linkage hooks on. when the governor would try to work, the nail would hit the side of the engine block and not let the linkage move.....tore the carb down I don't know how many times thinking some thing was wrong with it.....ugh, put a small cotter pin in and she was back up and running.....not sure if yours could have the same issue. ------------- Just cause it's orange don't make it a tractor, there's only one..Allis Chalmers |

Your problem may very well be a carb float problem since you state that the tank is full. However, I have found that, if the fuel tank is much less than half full, my D-17 will stall on a very steep hill. I have many of those steep hills here in my part of New York State. My WD and WD-45 are not quite as prone to this and I attribute it to the different shape of the tanks. On another note, My WD will lose oil pressure as well on a very steep hill even when the sump is full. The D-17 is more tolerant in that respect.

| I unscrewed the sediment bulb on my d17 and found a piece of gasket material in the upper end of the metal piece the sediment bulb clips to. I thought I had good fuel flow, it really runs out now. |

I'd do a comparative test on fuel flow: 1. test it on level ground vs 2. run the tractor up a hill until it dies, then re-test the fuel flow. That'd tell you whether the issue is a problem before the carb or not. Could still be something other than fuel-related, but it might help to narrow things down a bit. Good luck!

| I had this exact same issue on a Series II D-15 a couple years back. Only happened going uphill. It was the carb. Had it boiled out and that fixed everything. Been fine ever since. Hope that helps. |
