RUNNINGTHE ENGINE OUT OF THE WATERATHIGH RPM’s OR FOR EXTENDED PERIODS OF TIME. Whentheengine isnot
in the water there is no load on the prop so the engine can over rev. This will cause the connecting rod to break or stretch and break at a later date. Since
there is no load on the engine it will run at a higher RPM’s with less fuel and in turn less oil, this will not supply the rod bearing enough oil and will result
in breakage. Be careful. Only run your engine at low rpm’s while it is out of the water. Perform carburetor adjustments after running your engine in the
water. The only way to obtain the correct carburetor settings is to have the correct load on the prop.
IFYOU FLIP YOUR BOAT OR CAUSE THE ENGINE TO INGEST WATER WHILE IT IS RUNNING.This will cause the connecting
rod to break or stretch and break at a later date. This is caused by the piston trying to compress the ingested water which will not compress in turn placing
extreme loads on the connecting rod. This condition can also be caused by fuel flooding the engine and trying to spin it with an electric starter.
DO NOT RUN YOUR ENGINEATAN EXTREMELYRICH SETTING.AnABC engine needs to come up to temperature and running it at an
extremely rich setting for a period of time will cause premature wear on the piston as well as the rod to stretch and break. This is because the cylinder
is too cold and the piston is forced into the taper and sticks and is then pulled back down with the connecting rod. The normal warm up period will not hurt
the engine but trying to run it very rich will because of the accumulative effect of 15,000 rpm’s or 15,000 sticks and pulls of the rod per minute. The
damage may not be apparent initially but the rod may break in the future seemingly for no apparent reason.
DO NOT TRYTO BREAK YOUR ENGINE IN BYSPINNING IT WITHAN ELECTRIC STARTER OR DRILL MOTOR. This isthe
worst thing to do. You cause the same problems as running it too rich but even worse. By doing this the cylinder isn’t even close to the correct
temperature and there is no combustion to help the piston back down the stroke. So by doing this you are forcing the piston into the taper and then pulling
it back down with the connecting rod. Connecting rods are designed to take force in one direction only and doing this will cause the rod to stretch and
break as well as premature wear on the piston. The damage may not be apparent initially but the rod may break in the future seemingly for no apparent
reason.
THEABOVE IS TRUE WITHALL ENGINES, NOT JUST K&B, SO BEAWARE OF WHATYOUARE DOING AND THE

FLEXSHAFT CARE
An access hole is provided in the PTO (PowerTake Off) plate
on the lower unit for lubrication of the flex shaft. We recom-
mend that each time, before you run the engine, you lube the
cable with a mixture of 50% STP & 50% 20-50 weight oil. In
addition,we recommend that you periodically remove,inspect,
andre-lubethe entire flexcablewith K&B P/N 8449shaftlube

STARTING AND BREAK-IN
All K&B engines are produced to the highest industry stan-
dards and inspected before leaving the factory, but they are
not “BROKEN-IN”and will requireapproximately 30~45 min-
utes running before the full potential of the engine is realized.

slower, sometimes irregular, sputtering exhaust sound. The
exhaust gas will be smoky and probably contain small drop-

This is the setting you normally look for before launching the
boatbecause the enginewill run leaner whenin the water.

Important Information...
PLEASE NOTE: This engine is of “ABC” construction. That
means that it has an Aluminum piston fitted into a Brass,
Chromeplatedcylinder.
ABCtypeenginesareintentionallymanufactured witha “taper”
in the cylinder so you will feel a "binding” when the piston is
movingthroughthe top of its stroke.You may alsodetectwhat
seems like a dead spot or disconnected feeling of the crank-
shaftandyoumay even hear a clickingsound whenthepiston
is at this point.
Thesefeelingsandsoundsarethe result of the taper(binding)
in the cylinder affecting the required clearances in the con-
necting rod ends.All of these conditions are normal.
As the ABC type engine obtains operating temperature the
cylinderbecomes straight and the clearances between thepis-
ton and cylinder become correct. The straightening is due to
thetopofthecylinderrunningatahighertemperaturethan the
bottom, thus the top expands more.
Itisalsonormal for compression tosometimesfeelpoorwhen
the engine is stopped and turned over while still hot. This is
dueto the pistoncooling faster than thecylinder.If the engine
temperatureisallowed to stabilize thecompressionwill return
tonormal.
RUNNING THE ENGINE TOO RICH WILL RUIN THE FIT
If the operating temperature is not reached, the piston is pre-
maturelywornfromlackofclearance.Youdonotwantto"break-
in" an ABC engine at a very rich setting. Just a slightly rich
setting for the first 30 to 45 minutes of running is adequate.
WATERCOOLED HEAD
ThisK&B engine isequippedwith an watercooled head. This
requires the engine to be running through the water for the
pickuptubelocatedbehindthepropellertofeedthehead.The
engine can not be run outside of the water for extended peri-
ods of time since the head and lower unit require water for
cooling. Also, the engine needs air moving over the cylinder
finstocarryaway theheatofcombustion.CAUTION:Thehead,
lower unit and engine becomes hot during and after running
and can cause burns. Be careful.
For your information, your engine has been factory set with a

PRESSURELINE HOOK UP
Muffler pressure should be con-
nected to the tank from the nipple

CARBURETORSET UP
K&B engines are fitted with a vari-
able mixture carburetor which automatically alters both fuel
and air mixtures as it’s closed. Best and most reliable carbu-
retorsettingsare obtained after enginebreak-in.
Thecarburetor on the 3.5has a preset idlemixture and a high
speedmixtureneedle.
High Speed Needle ValveAdjustment:The needle,located
onthe carburetor assembly,controls all thefuel supply tothe
engineat the maximumthrottle setting. Itdoes not controlthe

ACTUAL STARTING
NOTE: The engine runs in a clockwise direction
when looking directly down at the flywheel. Thisis
opposite from an aircraft or car engine so the electric starter
mayhave to beconnected to your12 volt batteryin reverse.
WITHOUT battery connected, open the carburetor barrel to

viouslydescribed.Choketheengineby placingyourfingerover
the carburetor air inlet and slowly turn the flywheel over three
times clockwise. You should see fuel being drawn up the fuel
line. If fuel is not drawn into the carburetor, open the main
needleonemore turn. Fuelshouldbe drawn into carburetor.
Close the barrel to about the 1/3 open position and connect

4. Holes in the fuel line. The tear resistance of silicon tubing
is verylowandit’snotuncommontodevelopa hole where the
fuel line is assembled over the edges of brass tubing. If the
engine runs well on the first half of tank and then quits, it’s
almost always caused by a hole in the pick up line inside the
tank. Look for bubbles in the fuel line while the engine is run-
ning, this is a sign of holes somewhere in line.
5. Pressure tap in muffler plugged or restricted. Some fuels
contain oil that can collect on the interior of the muffler and
plug off the pressure tap causing the fuel tank to loose pres-
sureand starve theengine for fuel.This will causethe engine
torunlean then rich thenlean.Try running the enginewiththe
pressure line removed from the muffler to see if the problem
still exists.
MAINTENANCE
Whenyouarefinishedrunningforthe day,run your engine dry
byremovingthe fuel line atamoderatespeed or allow thefuel
tanktorun dry.It is best tosquirt someK&BAFTER RUN OIL
in the carburetor, then flip the propeller about 10 to 20 times.
Thisoilwillkeepcastorbasedfuelsfrom gumming and protect
internal engine parts from rust and corrosion. When storing
your model between running sessions, it is best to wrap your
engine in a rag or plastic to prevent dust, dirt and moisture
fromenteringthe engine. Theengineshould also be wrapped
in a rag between running sessions at the pond.
CHECKTIGHTNESSOFALLSCREWS
On a regular basis you should check all screws associated
withtheengine.Mounting,head,backcover,muffler,prop,lower
unit,etc.These screws must be properly torqued and not over-
tightened.Alwaysuseacrosstorquingtechniqueasmentioned
below.
BEARINGCARE
Your engine operates in an aquatic environment and uses fu-
els which attract moisture which will shorten the life of the
bearingsifnot cared for properly.
Acleaninghole is provided inthefront housing to aidinclean-
ing the front (or top) bearing. Simply place the spout tube of
WD40 (or similar product) up to the hole in the housing and
“back-flush” the bearing until you see fresh lube coming out
from under the flywheel. The bearing may also be oiled with
K&B After Run Oil using this same procedure. Do not use
WD40(or similarproduct) onthe lower unit.
FLEXSHAFT CARE
An access hole is provided in the lower unit for pre operation
lubrication of the flex shaft. We recommend that each time,
beforeyourunthe engine, you lubethe cablewithamixture of
50%STP& 50% 20-50weightoil. In addition,werecommend
that you periodically remove, inspect, and re-lube the entire
flex cable with K&B # 8449 shaft lube or equivalent for maxi-
mum cable life.
FUEL& CLEANLINESS
Alwaysuse fresh, clean fuel toprevent starting problemsand
poorengineperformance. We recommendthatyou use a fuel
filterinthe line betweenthetank and the needlevalveassem-
bly.Afilter will prevent foreign material from reaching the car-
buretorand causing aclog.
The engine will accelerate from idle to full throttle smoothly
andinstantaneouslywhenproperly adjusted. The enginemay
not idle well at a low setting or accelerate as quickly until it is
brokenin.
BREAK-IN
1.BREAK-IN running should bedone at aslightlyrich setting.
The needle valve should be set at a point just into this range
from a four cycle setting. Run the boat in the water at maxi-
mumthrottle for 2 minutes, then throttle backforapproximately
30seconds.Repeatthissequenceuntilapproximately30min-
utes of accumulated running time has been obtained.AVOID
MAXIMUMTHROTTLEFORLONG PERIODSOFTIMEDUR-
ING BREAK IN and AVOID RUNNING FOR LESS THAN 5
MINUTERUNS.
2. After the first 30~45 minutes, run the engine at a normal
peak needle valve setting. This should be a little on the rich
sidetoensureengine received proper lubrication.
BOAT INSTALLATION
Theengine must be mountedfirmlyto the transomofthe boat
usingthe machine screws andplate supplied with theengine.
Neveruse wood screws tomount the engine.
Careshouldbetakentothemountingpositionasrecommended
bytheboat manufacturer.
TROUBLE SHOOTING
Generallymostengine starting problems canbetracedto bad
glow plugs, weak starting batteries, or inadequate fuel sys-
tems.
GLOW PLUGS
The glow plug when connected to a 1.5 volt battery should
glow a bright orange. If the plug slightly glows the battery or
plugshouldbe replaced.
If the seal leaks around the center plug post, replace it.
Theglowplugelementshouldbeexaminedafterseveralflights.
If the element is deformed or touching the side of the plug
body, replace it. If the glow plug element is pitted or has a
frosty look, the engine is running too lean and continued run-
ning will seriously harm the engine.
FUEL SYSTEMS
The most frequent problems encountered with fuel systems
are:
1.Improperfuel tank location.Thefueltank should belocated
as close to the engine as possible.
2. Fuel pick up in tank is not free or in the wrong location. If
the boat runs rich, then lean, then rich, the pick up may be
picking up air, then fuel, then air, as the thrust of the engine
causes the fuel to be forced from the front of the tank to the
back.
3. Dirtorcontaminates in the fuel, tank,lines,filteror carbure-
tor. Many times a sliver of fuel line or other debris will cause
theneedleorifices to becomepluggedintermittently so acon-
sistentmixturesetting can not beobtained.Carefulinspection
andcleaningofthesepassageswillusuallysolvethe problem.
Don't use silicone sealant on areas of the carburetor that in-
volvefuel passages.

In time, the fuel filter can itself clog so we recommend you
removethe filter from theline from timetotime and tocleanit.
AFTERRUN OIL
Werecommendthe use of RJL orK&Bafterrun oil (or equiva-
lent) after each days operation.After the engine is run dry of
fuelsquirtseveraldropsinthe glowplugholeand severaldrops
intothecarb intake of thestillwarmengine is sufficient. Briefly
hit the flywheel with your starter to distribute the oil evenly
throughouttheengine.
ENGINECLEANOUT
If dirt or water does enter the engine do not turn it over until it
hasbeenflushed out completely.Alcohol is recommended for
this.DONOTUSE carburetor cleaner or chlorinatedindustrial
solvents as they may attack the plastic parts of the engine.
Thefollowing steps maybeused as adisassembly/assemble

1.Removecarburetorandglowplug.
2.Removethe engine from lower unit.
3.RemovethePTOcover,muffler, and cylinderhead.
3. Flush engine out completely using alcohol or mild solvent.
4. Install PTO cover, muffler, and head. Insert screws into
head and tighten until they just touch the head. Then tighten
them in a cross pattern sequence. Tighten the screws only
slightly, repeating the sequence a number of times until the
screws are tight.
5. Remove the flex shaft and grease with K&B flex shaft lube.
