  • Forgot to shut off fuel
  • OK, it appears that I forgot to shut off the fuel the last time I used the tractor. How can I test if fuel got in the oil? I pulled the dipstick and put some of the oil on my fingers and did a sniff test but that didn't really tell me anything. The fuel bowl appears to be full. The hose from the air to the carb isn't tight; I don't have a clamp on it.

    Or should I just dump the oil and replace it and not guess? I had used synethic oil and the oil is nice and clean since it hasn't been changed that long ago; hate to lose the money but don't want to ruin the engine.

    I need to get one of the electric shut-off valves; I am always double checking the fuel shut off but I guess I got distracted the last time. I needed to haul wood today but maybe not.

  • OK, wood hauled, mission completed. Oil pressure was around 50 cold engine; it drops after running the engine for a few hours. Started great. I love this old 8N I got from Dad and Mum and I would hate to hurt it over something stupid.

  • If it sat for months and didn't drain the gas tank, it didn't get gas in the engine.
    The gas tank would be empty within a couple of days if it were leaking.

  • The oil level is at the full mark. I have had issues with this carb float etc; so I turn the fuel off if I stop the tractor to do work. Tractor has been sitting for a few months; most of the winter. I don't know what synthetic oil smells like; I don't really detect gasoline smell on the dipstick. Tractor is level. I have not notice fuel dripping out of the carb at the air intake and there is fuel in the tank; so if fuel was flowing it should have drain the tank after all these months; I should have smelled gasoline when going by the tractor. It is outside in front of the shed under a canopy and I have to go by it to entry the shed. So I am probably safe to start the tractor?

  • Whether you have carb float issues or not, it's a good (and safe) idea in my opinion to shut off the fuel at the tank every time you finish a day's work, particularly on vintage engines.

  • While it is a smart idea to shut off the fuel, if you have no visible leakage, oil level is on the mark, and you are not smelling gasoline on the dip stick, I would say you have no problem.

    Try to remember next time!

    Good Luck,

  • With the up draft carbs being under the manifold it takes a lot of gas to fill the carb, air intake hose and manifold to the point that gas will go in the engine. So if you don't have gas running out the intake hose at the carb it hasn't gotten into the engine.

  • Re: Forgot to shut off fuel
  • The best way I found to remember the shut off valve is to follow this sequence on shut down:

    After I park the tractor, lower lift, put trans in neutral, set parking brake, then I let the engine idle while I shut the fuel valve off. When the engine starts to sputter due to running out of gas, I turn the key off. Since I got in the habit of doing it this way, I haven't had anymore trouble remembering to shut the fuel off.

    If you can't smell gas on the oil from the dipstick, might not have leaked into the oil. You might be lucky. The oil level should be an easy indicator.
