Of course, by nature, they are adjusted incorrectly at the factory....<div><br></div><div>There’s several possible explanations and anything I might say is just a guess but one procedure to try: let it roll over 3-4 times with slight throttle, full choke and THEN turn on ignition. If the issue is flooding (for whatever reasons) this will never work. If it’s starvation(for whatever reasons) this will improve starting behavior. This will rule out half of the possibilities. <span style="caret-color: rgb(0, 0, 0); color: rgb(0, 0, 0);"> If it makes no difference then the issue may indeed lie elsewhere. </span> Also, if it works, you won’t have to fix it.

It always does start, eventually, but if the weather is cold it’ll take maybe five or six or eight attempts, with each one resulting in a few pops or a second or two of running before it dies. I always think I just need to find the right amount of choke vs throttle, but I don’t know whether I’m really finding it or whether the engine just gets warmed up enough by the repeated attempts that finally it settles down and is just plain ready to start. In warm weather it typically fires right up with no hesitation.<o:p></o:p></p><p class="MsoNormal"><o:p> </o:p></p><p class="MsoNormal">12 volt battery is well charged, and a few years ago I had the starter rewound for 12 volts, so there’s no shortage of cranking power and it turns the engine over nice and fast (but not crazy fast like it used to with the 12V battery on the original 6-volt starter). <o:p></o:p></p><p class="MsoNormal"><o:p> </o:p></p><p class="MsoNormal">It does have pretty high compression, resulting I assume from a rebuild shortly before I bought the tractor ten years or so ago, and which helps it put out about 55 hp on the dyno. I can’t remember the compression numbers right now, but I remember checking compression after buying the tractor and thinking “Wow, those are some high numbers, and all four cylinders are just about dead-on equal.” When hot the engine typically diesels at shut-down unless I let it sit and idle for several minutes, so I’m wondering if the hard cold starting is related. <o:p></o:p></p><p class="MsoNormal"><o:p> </o:p></p><p class="MsoNormal">Anybody have similar experiences or recommendations? The other thing I was wondering is if maybe the non sequitur is out of adjustment, but I can’t find the factory specs for it in the service manual.<o:p></o:p></p><p class="MsoNormal"><o:p> </o:p></p><p class="MsoNormal">Dean Vinson<o:p></o:p></p><p class="MsoNormal">Saint Paris, Ohio<o:p></o:p></p><p class="MsoNormal"><o:p> </o:p></p><p class="MsoNormal"><o:p> </o:p></p></div><span>_______________________________________________</span><br><span>AT mailing list</span><br><span>AT@lists.antique-tractor.com</span><br><span>http://lists.antique-tractor.com/listinfo.cgi/at-antique-tractor.com</span><br></div></blockquote></div></div></body></html>
