How to Set the Points on Johnson Outboards Place the motor, if trailered, in an accessible spot. Place a flywheel strap around the perimeter of the flywheel and hold it taut. Pull the flywheel off. Use a flat-head screwdriver to loosen and remove the two screws for one set of points.
How do you set the timing on a Johnson outboard motor?
Remove the trigger link rod socket from the ball stud by hand. Remove the socket from the ball stud and decrease the length of the link rod to increase the timing, or increase the length of the link rod to decrease timing speed. Place the socket back into the ball stud once the timing is set.
How do you tell if timing is off on outboard?
What are the symptoms of a bad timing? Engine Has A Ticking Noise: A series of pulleys attach the engine timing belt the engine’s camshaft and crank, allowing the crankshaft to power the connecting rods that are attached to pistons. Engine Won’t Start: If the engine timing belt has broken, it won’t be able to start.
What does a condenser do on an outboard motor?
A condenser is part of the ignition system used on most small engines. The condenser is physically the same as a high voltage capacitor used in other types of electrical circuits. The small engine condenser stores a high voltage charge. A set of contacts are used to release that charge to the spark plug.
What is a dwell meter?
A dwell meter measures the angle of rotation of the cam through which the points are opened and closed, and registers the dwell angle – the period when they are closed. The meter can also, of course, be used when fitting new points. A dwell meter is usually part of an instrument used for various mechanical checks.
How do you adjust the idle on a Johnson 115?
Locate the spark plug lead underneath the panel near the ignition. Attach the tachometer to the lead. Wait for the Johnson outboard to automatically drop into low idle. The engine will make noticeably less noise when this happens.
How do you time a 2 stroke engine?
Timing is set on a 2 stroke by adjusting the stator. You need a dial indicator in the spark plug hole. Set TDC to 0 on the dial indicator, then turn the engine over counter clockwise until the timing marks line up. The reading on the dial indicator will tell you the timing.
What is quick start on a Johnson outboard?
QuikStart (a 10° timing advance) activates as long as the engine RPM is below 1,100, the engine temperature is below 105 F and the yellow/red wire from the starter solenoid is not feeding 12 volts DC to the power pack all of the time.
What are the symptoms of a bad timing?
Symptoms of a Bad or Failing Timing Belt You Hear A Ticking Noise Coming From The Engine. Your Car’s Engine Won’t Turn Over. You Notice An Oil Leak Near The Motor. You Experience Exhaust Issues. Your Revs Start Acting Up.
How do you set engine timing without timing marks?
How to Set the Ignition Timing With No Timing Marks Mark the spark plug wires for the cylinder number using a short piece of masking tape on each wire. Rotate the engine clockwise and observe the valves on the number one cylinder.
What are the symptoms of a bad condenser?
5 Symptoms of a Bad A/C Condenser: (1) Lukewarm Air from Vents: (2) Burning Smell: (3) Overheating While Idling: (4) Noticeable Leaks of Refrigerant: (5) Warning Lights on Dashboard:.
How do you know if a point and condenser is bad?
Here are some common symptoms that hint towards having failing points and condenser: Vehicle not starting. If your vehicle will not start, it is possible there is a problem somewhere within the points and condenser. Engine will not fire. Engine runs rough.
How does a points condenser work?
The condenser absorbs the energy and prevents arcing between the points each time they open. This condenser also aids in the rapid collapse of the magnetic field. At the same time, breaker points close to the complete the primary circuit, allowing primary current to flow.
How do you advance timing on a Mercury outboard?
Adjust the idle timing screw so that it is 2 degrees before top dead center. Turn off the engine. Start the engine again, following the same steps as in the beginning, making sure you’re in neutral. Adjust the maximum timing screw or timing of throttle at wide open (WOT) so that it is 24 degrees before top dead center.
How do you set dwell points?
Turn the key ON and crank the engine. Using a feeler gauge to get close, adjust the points to the desired setting according to dwell readings and tighten the points. Crank it again to be sure the dwell angle is still correct. You can now go on to set your timing.
What happens if ignition points are too close?
As they close, current from the ignition switch flows through the contacts into the coil’s primary windings and then off to ground. All that current flowing across the points doesn’t like to stop suddenly, and can initiate a small arc, which eventually erodes the tungsten contacts.
How do you adjust dwell angle?
Refer to your owner’s manual for the correct dwell angle setting (i.e. 30 or 32 degrees). Turn the adjustment screw in (clockwise) to increase the dwell, or out (counterclockwise) to decrease the dwell. Once the needle reads the correct number, withdraw the Allen wrench and shut the engine off.
How do you adjust the idle on a 2 stroke outboard?
Adjust the idle stop screw on the side of the carburetor near the choke cable, turning the screw with a screwdriver until the vacuum gauge is reading about 600 rpm. Turn the idle mixture screw counterclockwise 1/4-turn at a time until you hear the engine begin to stall out, and turn it clockwise 1/4-turn.
How do I adjust the idle speed on my Evinrude outboard?
The ideal idle is somewhere near the midpoint of this range, about 750 rpm. Loosen the lock nut on the idle speed adjustment screw with a small adjustable wrench. Turn the screw clockwise with a screwdriver to increase the idle speed; turning the screw counterclockwise decreases the idle speed.
