<div>One thing on my side now is that it will be 50 degrees
today and 60 tomorrow. I may not need anything extra. I do
know that one problem is the thick oil in the tank and it
not having a way to clutch out the pump for starting.</div>

<p>Remember the old fire triangle? Fuel-Air-Heat.</p>
<p>With the ever more restrictive regulations filtering
down to the smaller engines the manufacturers have had
to lean out the mix as far as possible. If you were to
put a pyrometer on one my guess is that at operating
temperature they are running on the lean side of peak.</p>
<p>As air temp drops it gets more dense but without a
choke to compensate the mix is just too lean to light
off. To make things worse they have taken all of the
adjustments away from the end user to prevent us from
becoming criminals against the regulations. I suspect
it also makes the carbs easier and cheaper to
manufacture. If a bad one slips through, just replace
it or the engine because it is cheaper than figuring
out the problem. We see this in a lot more then
carburetors.</p>
<p>Changing to a lighter hydraulic fluid will help make
it easier to spin the engine faster when pulling the
starter. I am not sure if that will help make a hotter
spark or not considering it probably has electronic
ignition anyway. Faster starting RPM could help with
sucking in more fuel each stroke but then that means
more air to, so back to lean.</p>
<p>I suspect that Farmer's engine sputters once in a
while is that the raw fuel builds up enough in the
cylinder to cause a rich enough mixture to fire once
or twice. Once that is burned off, back to square one.</p>
<p>I am not sure that adjusting the valves would help
any unless there is a way to lengthen the duration.
Taking out all the backlash might cause the valve to
open a fraction sooner, but once everything is warm
and expanded there is a risk of it not closing fully
and burning the valve or seat.</p>
<p>To get a more rich mixture for starting you could try
to restrict air (like the old choke plates did) or add
fuel like a primer does.</p>
<p>I have a Knipco stye heater that will not light off
at any air temp unless I use both hands and cover as
much of the air intake as possible. It lights in less
than a second and then runs fine. I have tried
different nozzles and moving the igniter around, but
it still needs less air to get going.</p>
<p>On the 1978 motorcycle I once had it was a victim of
early tampering with emissions on motorcycles. When
new it would not start on a cool day and it had a
manual choke. I rigged up a way to inject a little
ether into the airbox that was buried under the seat.
Had to put 10,000 miles on that bike before it got
over that problem.</p>
<p>The idea of using an unlit torch to add a little fuel
sounds like a good one. Red Green would just slap a
little piece of duct tape on the air intake until it
warms up.</p>
<p>Best of luck to Farmer getting this working.</p>

Just a thought, my log splitter was hard
to start in cold weather, until I changed
the hydraulic fluid from the OEM fluid to
transmission fluid,a whole world of
difference.<br>

downloading manuals from the Briggs

I do. The other thing I'll mention
is the good old unlit propane torch in
the intake trick. That's my go-to
when they're almost trying to start.
There's spark and fuel but the modern
carburetors are set lean for emissions
and it just seems that the choke
doesn't quite get the mixture rich
enough.

<div>We have a log splitter a
couple of years old that has a
OHV CR950 Briggs. It only has a
few hours on it but has become
quite hard to start (recoil
start). It is way too recent for
my knowledge base... It seems
that most things are these days.
Apparently the OHV Brigg's have
a cam bump "compression relief"
I also understand that there is
an important valve adjustment
procedure that can normally
improve starting problems. We
can't find a site that gives a
clear and understandable
explanation of the procedure.</div>
<div>Does anyone know of a site
with a clear description of how
to do it? It will usually start
if it is sitting in the sun and
the temp is at least 50...
Yesterday at 45 degrees it
"ALMOST" started 837 times... It
keeps firing enough to keep you
trying and trying...<br>
