Groove on front pulley Distributor Rotation: Clockwise Cylinder Numbering front to rear: Adjusting Ignition Timing When checking engine timing with a strobe type timing light, disconnect the vacuum line from the carb to the distributor. Engine should be at idle speed. Connect timing light high voltage lead to wire going to Number 1 spark plug and the appropriate low voltage leads to the battery connections per timing light instructions. Be sure to check polarity of connections Loosen distributor hold-down bolt and adjust timing by twisting distributor until timing marks line up between groove on pulley and indicator.
Automotive Timing Lights
If an engine has breaker points it will have timing marks. I usually remove the blower housing, find the timing marks and stick on a piece of reflective tape. An engine can be run for a short time with the blower housing removed. Some engines have a removable screen which exposes the flywheel. Manual start engines will need a rope or strap wrapped around the cup to start them with the blower housing and recoil starter removed.
The link that I sent you has an upgrade for Kohlers, but can be installed on some other makes, that is partly solid state and uses the breaker points as a switch to trigger the spark in the solid state device.
Setting the timing on the warmed-up engine, the cam cover is warm-hot, and gets hotter as the engine runs. Placing a small towel on the cover, on top of the spark plug wires, provides a convenient, insulated arm-rest while attacking the cam sensor bolt.
Here is some stuff from the Bronze training. A typical CDI module may look something like this on the inside, simplified of course: As the flywheel goes by the armature, the magnetic lines of flux travel up through the armature and induce current flow in the primary windings. The energy is stored in the capacitor, and the diode prevents the AC current from bleeding off.
When the chip tells the transistor when to close, the capacitor discharges and the current flow in the primary cuts through the secondary and fires the plug. I don’t know what kind of voltages are at work in the primary, but it typically has around turns of wire in it, but the secondary has like 20, turns so you get a step up transformer effect, so a module can develop 15k volts depending on the design.
Since the capacitor stores the energy, the flywheel can roll on by the module, and the chip will decide when to fire the plug by comparing how often the flywheel comes by to a built in quartz clock, to determine RPM. It changes the timing based on the software it was programmed with when it was made. At 12, rpm the plug is firing the spark plug times a second, so all this is happening really fast but they tell me electrons move at the speed of light, and microprocessors can think really fast, so I guess it is all relative.
Here is the timing curve used to illustrate a typical curve for a module with a rev-limiter in it, shown by the red line. The blue line is a module with no advance. STIHL does not use an ignition rev-limiter in any saws, but they do in most all line trimmer engines.

These were different than Miriam’s situation, however, if the L-rd can make Sarah at 90 give birth, then it is no problem for Him to cause a virgin to conceive. Thus, all these women conceived through Divine intervention. I will put enmity animosity between you Satan and the woman, and between your seed and her seed; it shall bruise your head authority , and you shall bruise His heel. Women do not have “seed”, men have “seed”; this points to a supernatural occurrence.
May 03, · Sewing machines are surprisingly delicate pieces of machinery. When the bobbin or needle gets pulled out of timing with the rest of the tool, the machine is useless and becomes a danger when the needle breaks.
Tus ojos Which part of your body lets you read the back of a cereal box, check out a rainbow, and see a softball heading your way? Which part lets you cry when you’re sad and makes tears to protect itself? Which part has muscles that adjust to let you focus on things that are close up or far away? If you guessed the eye, you’re right! Your eyes are at work from the moment you wake up to the moment you close them to go to sleep.
They take in tons of information about the world around you — shapes, colors, movements, and more. Then they send the information to your brain for processing so the brain knows what’s going on outside of your body. You can see that the eye’s pretty amazing. So, come on — let’s take a tour of its many parts. The Parts of the Eye You can check out different parts of the eye by looking at your own eye in the mirror or by looking at but not touching a friend’s eye.
Some of the eye’s parts are easy to see, so most friends will say OK. Most friends won’t say OK if you ask to see their liver! The eyelid protects the front part of the eye. The lid helps keep the eye clean and moist by opening and shutting several times a minute.
CJ timing confusion again.
You MUST definitely use a timing light to adjust your timing correctly. The only way a timing adjustment does make sense is: To adjust your timing: Warm up your engine to normal operating temperature.
Jul 06, · Socially inappropriate motoring information, available in 1qt increments. That is what i did last year, i stacked #1 Cyl coil on top of the bottom piece of another coil and made this tall coil with an exposed portion in the middle, where i clamped the timing light.
Yes, timing lights measure both timing and RPM – mine does. And, it has a 2 and 4 cycle setting for the reasons mentioned in the discussions. I knew that the wasted spark design would not affect the timing function. But I expected it to read twice the real rpm when on the 4 cycle setting because of the wasted spark design and the fact that it uses an inductive pick up on a spark plug. Thanks for confirming that for me. The problem is, I dont think it actually is reading twice the rpm – but rather the correct RPM, just based on the way the engine sounds, so I am going to find another way to check it, as one person suggested.
I am not sure that a conventional tach that connects to the points will work on this magneto design, however. It is in a gravely clean-cut 70, and its rated at A I mentioned in a previous post, it has a single stator coil, just one, not a ring of them, with one pair of magnets in the flywheel, and a separate, 4 volt ignition coil. You can still buy NOS stator kits and 4 volt coils for this.
12 vdc Inductive ignition timing light bulb weak flash
I have on my possession 4 timinglights: All guns reported a different timing reading among them! The Actron is actually the one i think is most reliable, but then again, there’s about degrees difference between these 2, one is brand new, the other is a couple of years old and took a header once and stopped working, i put it back together for this test and it seems to work normally. The Equus digital one is a marvelous piece of equipment, no matter what i did with the timing settings, locked, unlocked, using reversed edges, etc.
I actually had to replace it with a pickup clamp from another damaged light, which is identical to the pickup clamp on the Actrons.
Digital dwell meter hook up. Hi all, I also checked timing and advance with a timing light and now all is in specs. (timing seems a little bit unsteady in RPMs range but I assume it’s normal for a 40 Y.O. unrebuilt distributor to have an oscillation of degrees).
Unfortunately, it was misplaced in some of the server outages at the NCCC site, where it was housed. I finally remembered to check the Internet Wayback Machine for the page, and here it is! Unfortunately, a few of the pictures did not get saved in the archive. I will try to see if I can find them on my computer But below, we have the text and most of the pics from it. Son of a gun.
The NCCC site, where the pics were hosted, is having problems now. I have swapped in the Webarchve pictures for all of the ones I can find If your timing is too far advanced, you can get “pinging”, which is a sign of detonation–and detonation is something you don’t want in your engine.

This timing light is a strobe light used for checking ignition timing and fires whenever the spark plug does to maximize engine efficiency. Some older timing lights require the removal of the spark plug boot in order to attach a direct pickup between the wire’s terminal and the center conductor of the spark plug.
The Volt battery supplies the primary voltage to the coil and ignition unit if electronic. When the coil is activated by the trigging device contact points, electronic module, crank trigger, magnetic reluctor, or other type of trigger , the coil builds and releases a secondary voltage which is sent to the distributor via the coil wire. It does this at a very high rate of recovery speed. The secondary voltage or spark travels through the distributor to the appropriate spark plug by means the rotor and a plug wire, where it jumps the spark plug gap and ignites the mixture.
Understanding Ignition Timing Ignition Timing is the relationship or the position of the piston and when ignition spark occurs. If the spark occurs too late, the ignition occurs when the piston is traveling back down the cylinder, resulting in wasted energy, unburned fuel, higher emissions, and power loss. Therefore it is obvious that the ignition spark must occur at precisely the right moment to achieve maximum power and efficiency. On older engines like our inline sixes, and most race cars with aftermarket distributors, the ignition system uses a simple mechanical advance or a combination of mechanical and vacuum advance built into the distributor.
Both the initial and the advanced timing, or a combination of total timing can be adjusting for your engine’s optimum performance, which is referred to as the timing curve.
How To Adjust Base Ignition Timing
First, please try to use proper punctuation. It makes your post easier to read. As far as the timing issue goes, you really need a light. Go to Harbor Freight, or order from them online.
May 21, · Hook your light to #1 plug wire and start the already warm engine. Aim the light down from above at the crank pulley and scale. Move the distributor until your painted mark lines up with the spot on the crank pulley.
Not only does it reduce the burden on one’s pocketbook in regards to fuel savings, but a good tuneup also reduces tailpipe emissions. Below is information you may find helpful in tuning your Dodge Truck. The proper amount of fuel and air compressed at the ideal moment produces power. In this piece we deal with igniting the spark that lights the fire. Ignition timing is typically split into three types.
The first is ignition timing that is, the amount of spark lead that is set using a timing light aimed at the harmonic balancer with the engine at idle. The second type is mechanical advance, determined by the distributor’s mechanical advance system. The final type is vacuum advance, determined by the vacuum canister attached to the distributor.
Since a mechanical distributor is still the most popular form of ignition, we’ll focus on it. But before we set these values, it’s important to understand how these events interact. Initial advance is set by moving the distributor in the engine.
timing without a timing light*
I bought an inductive timing light to time the ignition on several motorcycles including my KZ The light was used and came with no directions. I looked for instructions online and still had questions. An inductive timing light is pretty easy to use when you know how. The other clamp goes on your ignition wire, and here is where I ran into problems.
This way you can return towards stock without hooking up the timing light again. I say this because despite what MM says, every Miata seems to tolerate a different amount of timing. If it pings just sneak back towards stock ’til it stops.
Timing belt changes – some useful tips Toothed rubber timing belts were used on many Land Rovers through the s and 90s, including Defender 2. However they will eventually break if not changed, and this will do a lot of damage to the engine. So belt changes are not something you can just ignore. With garages charging anywhere from to or even more for a belt change, it is possible to save a fair bit of money by doing it yourself, but the procedure isn’t always as straightforward as the workshop manual suggests.
This page is not intended to replace the workshop manual instructions, but to provide a bit of additional information which will help you do the job right first time. It goes without saying that the job should be done properly. Just replacing the belt and not the tensioner and idler is a false economy: Leaking oil seals on the crankshaft or camshaft will soak the belt in oil and reduce its life.
And if the belt tension is set incorrectly, the belt will have a short life and other components such as the injection pump may be damaged as well.
