  • Runs great, looses power under load
  • I was updating my 2n so I converted to 12 volt, installed a new carb, new distribute and a new governor. Runs very good until a load is put on the engine. She looses almost all power? What is wrong?

  • Sean, you didn't say if the tractor was working properly before you installed the new parts, or if you installed the new parts in hopes of correcting the problem.

    Please clarify.

  • Wow.

    I can't think of a better way to get a poorly running tractor than to change all of those components at the same time.

    They all not only need to work correctly, they need to work together.

    I'll assume you bought the carb, distributor and governor new and did not have your oem parts rebuilt? Iíve been working on old cars, trucks & tractors now for over 50 years. Whenever possible, I get OEM component parts rebuilt. Given the high probability that any new component part purchased for an N tractor is made somewhere overseas w/o adequate quality control, chances are very good that you will be disappointed. If indeed all 3 components are new, I'd say the odds are 7 out of 10 that at least one of them is paper-weight quality.

    So, mistake #1: replacing all components at once

    Possible mistake # 2: buying new parts rather than having them rebuilt.

    Possible mistake # 3: Failure to adjust the components.

    Some things to check:

    Firing order (1-2-4-3, CCW)

    Governor adjustment (per the I&T FO4 manual)

    Carb adjustment

    Points gap & timing. (did you set the gap and check the timing before you installed the distributor ?)

    Post back w/ questions or results, pls.

  • Why did you switch to 12 volts and what all did you do there? I wouldn't call an 'update' as doing a 12-volt convulsion, but since the damage has been done, see the LINK below and download a copy for your future reference files. JMOR has put together a super document on every CORRECT way to wire these old vintage Ford Tractors. Many 12-volt jobs are done incorrectly and for the wrong reasons. Non-running/non-starting/rough running issues are often deduced as an electrical problem and the thinking leans towards just putting a 12-volt battery in and all is good with the world. 87% of the time the true root cause is not electrical at all -fuel, spark, and combustion are all needed to run and at the right time. You changed a lot of things all at once and probably should have just done one system at a time, at least I would have.

  • Re: Runs great, looses power under load
  • Sounds like he won't be back.
    All you idiots jumped on him with both feet because he changed a few parts.
    So why would he return.

  • First check firing order. Wires should connect 1,2,4,3 from front to back. Often 4 and 3 get swapped and it will run just like you describe.
