  • Troubleshooting help please...
  • I come here when I find any problem, with either of my N`s...
    Beins as we have very good combined experience amoungst us...
    It`s mowing season again and I`ve been busy doing just that too...
    Just these last two times out I`ve found after about an hour running time my 50 model will "bog" badly and not get the RPMs quick as it did when I started...
    IF a tree bogs it down or if I brake to turn around it seems to "lose power"...
    Yesterday, I was thinking the fuel tank was getting low, so I hauled bugger back to the barn to get gas, I checked & filled it - BUT!
    It still had a couple gallons in it, so that was NOT the problem...
    Then today I paid attention to when it started doing it, and found 45 minutes to an hour, is when it started acting up...
    It was very dirty and I got to thinking the governor linkage/spring might be clogged and not working correctly so I pressure washed her and she looks good! :)
    I`ve not been back out mowing since, so I dunno??
    I did pull the cap off the distributor to look at points/rotor and didn`t find anything awry...
    I`m thankful this didn`t give a problem early in gtting started mowing, and waited until the last of it...
    Yes! She could stand a tune up probably,

  • My 2 cents and take it for what it's worth.
    You washed it and it ran better.
    You either cleaned the muck out of the radiator fins or cooled of the coil.
    I would go with coil.

    Never use water on an electrical fire.

  • Re: Troubleshooting help please...
  • Yes, Bruce, I thought that MAYBE the coil is heating up and breaking down...
    I`ve read this can be a problem, both here & the Motorcycle forums...
    I do have a spare coil (somewhere) I can swap out to see...

    Thank You ALL for your patience with me,
    Dennis

  • Re: Troubleshooting help please...
  • Mine did this last year. Running great, pulling a 5 foot shredder. About an hour in it started lugging down like it was going to die. Being about as far away from anywhere to get to tools, gas, etc. I wanted to keep it running. It quit anyway. So, I got off and looked at things, like you were describing.

    Solution to mine was opening the fuel shutoff valve another couple of turns. I had been using it with the valve at about three turns open for quite a while. After doing that it ran great again and has done OK since.

    Not thinking yours is the same, but that's what worked for me. Why? Well, I don't know but I think maybe the valve is old and cruddy, maybe the screen in the tank is gunked up some. I had a heck of a time getting the thing to stop leaking the last time I had it apart, so the thought was replace it next time. "next time" hasn't come yet though.

  • Front mount or angle mount distributor? 6V/POS GRN or 12V Switch out job? Many 'assumed' fuel issues turn out to be electrical and vice versa. I advise to not start replacing parts until you determine the true root cause problem and then only if defective and cannot be rebuilt. Baby steps; one system at a time. I'd start with the fuel flow test. Fails? Troubleshoot fuel system from tank and sediment bulb down to carb inlet elbow. Passes? Move onto electrical. Spark test pass or fail? Verify wiring is correct whether 6V or 12V. Realize that 99% of all non-starting/non-running issues are due to incorrect wiring. Be sure to do the fuel testing on a COLD non-running engine. Avoid gas spills. Dry up before dong any electrical/sparking. Leave distributor alone for now. I'd do a compete fuel system test first. I concur with Bruce(VA) - you cannot simply 'look' at the distributor and points and tell that way if there are any hiccups.

  • Re: Troubleshooting help please...
  • 12V neg ground and Shifty th` Fifty has the side mounted dizzy...
    Yes, I`m going through our troubleshooting as we discuss this thing...
    As I mentioned, I hadn`t been back out after the pressure washing since "dark thirty" came before I could...

    I took her out after our "Facebook Church" meeting and mowed the last field...
    She did it again, so, obviously, I didn`t fix anything by "looking at the points" or cleaning her governor spring and levers...
    "Looking at points" consists of opening and closing the gap with power ON to see IF they`re working...
    They`re prolly fairly close on gap, cause She Runs good ;)
    Then, whilst mowing this morning, I was thinking along the lines that MAYBE the coil is heating up & breaking down too...
    I just like to check with our Gurus to be certain I check everything... Y`all have "Fixed many" for us along the years I`ve been associated with ya...
    I ALWAYS get get that "second opinion" before I take anything apart, and some of y`all KNOW > I`m too much a Cheapskate to "throw parts at a problem"...

    AND when working on her I have Y`all with me, I put my N tractor Club ballcap on too, Dennis

    Thank You Guys,
    I`ll continue along these routes you suggest, Thanks again
    I reckon I might $pring for point$ and plug$ though, she`s been running on these since I got her...
    AND Remember? I bought this - $600 - 50 model for parts for my 49er, BUT she runs too good to part it out :)

  • Re: Troubleshooting help please...
  • I might mention that >
    I was told by a mechanic that the cam bushings are worn, it`ll knock at times...
    This is a local mechanic fella, who worked on the tractor before I got it, is very knowledged in these Ns...
    Said something about the cam will shift to the "end" ???
    Slide or move forward and back???
    It doesn`t knock all the time,
    Dennis

  • " I did pull the cap off the distributor to look at points"

    You have better eyes than me if you can look at a set of points and see if the gap is correct at .015.

    These tractors are pretty simple machines; itís usually pretty easy to get them running with some basic troubleshooting steps.

    You could have a spark issue.

    You could have a fuel issue.

    Donít guess. Troubleshoot. See tip # 13.

    You need to answer 2 questions before you do anything else:

    With the bolt in the carb bowl removed and the gas on, will the fuel flow fill a pint jar in less than 2 minutes?

    Next, get out your adjustable gap spark checker * , open the gap to 1/4", hook it up, turn the key on and crank the engine. Does the spark jump 1/4"? Post back with the answers.

    And do not buy a new part for the tractor until you can answer this question: how do I know the part on the tractor is defective?

    Once you narrow the problem to spark or fuel, post back and tell us what you found (and how you found it) and you will get plenty of help to get your tractor running.

    * Don't own an adjustable gap spark checker? Buy one! Not a test light! Until then, take an old plug, open the gap 1/4" ground it to the head & look for spark. Itís not the color of the spark that counts; itís the distance it jumps.
