<div>Hi Dean:</div>
<div>My Super M and Super MTA both tend to be cold natured at
start up and when working hard prone to dieseling at shut
down. Both have thin-wall sleeves and oversized pistons. To
start up "cold" I typically open the throttle maybe about 5 %
or less and use the choke heavily. For the dieseling I keep
the idle speed backed off so that the throttle plate shuts
completely when I shove the lever all the way forward. I keep
a small paint mark on the quadrant back a few notches as an
idling setting. They can't diesel if they can't get any fuel.
:-) It has always served me well.</div>

<p class="MsoNormal">My Super M is hard to start in cold
weather. 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.</p>
<p class="MsoNormal"> </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). </p>
<p class="MsoNormal"> </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. </p>
<p class="MsoNormal"> </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.</p>
