WSK 125 - ignition setting, break on the circuit breaker

Question

Hello everyone, I have a question, when should the platinum start to open, how is the piston at the top or 0.3mm before TDC. How would someone measure with a caliper where the plunger is, like the platinum is open. I don't want to spend money on some meters. I only have an electric caliper...

Platinum plates are to open 3 mm before TDC, and the gap on plates is 0.4 mm.

The flash point is 3 mm before TDC, which is when the platinum is to open and the gap is not so important that they open and close clearly, sometimes you need to improvise because the equipment is worn or of poor Chinese quality. They recommend 0.4 mm, I never measure it, currently I use a dial gauge and a strobe lamp for such purposes. Thanks to this, I detected and corrected the problem in the ignition of the Chinese cd and wsk, as if you would write any problems.

They are to open 3 mm before TDC of the piston - as my colleague wrote above.

If you increased the break on the circuit breaker and did not check the ignition after that, you are too early now. You start by setting the gap and then the ignition point, and you don't move anything else. Check also, replace the capacitor.
It will be difficult to help you because I can see that you cannot judge the condition of the circuit breaker and it should work precisely. Ask someone on the spot who has an idea and will assess in real life what is wrong with this wuesce. It cannot be done at a distance.

Exactly as a colleague writes, each change of the contact gap causes a change in the ignition point. And how do you check the flash point, what method do you use, because they are different. Do not move the carburetor when it was fine, I will only suggest that for such tests I use a drill and a socket wrench as a starter, a magneto cap and spin, it is a pity to strain and kick with my foot.

Remember that the ignition must be between 1.5 and 3.5 in order to fire properly, but you have to be sure it does. Write how you check the ignition, I will tell you how to check the correct operation of the circuit breaker contacts.

The glow color of ionized gas depends on the type of gas and its temperature. The spark should not be red. The break on the circuit breaker must not be too large, because the contacts may not be short-circuited at maximum speed. Such advice from the old days. I know from my own practice that a too small break on the circuit breaker means continuous sparking of the contacts, which manifests itself in disturbances in the AM bands and such a motor can be heard on the radio from several hundred meters. The gap between the candle electrodes seems too small to me, but I would have to refer to literature to refresh my memory.
The breaker opening, i.e. the moment of ignition, is checked by a colleague, e.g. with an ohmmeter. In systems with battery ignition, a 5W bulb was turned on in series with the circuit breaker and it went out when there was a break and ignition. A less precise method is to stick a tissue paper between the contacts of the circuit breaker and try to pull it out - when it is successful, we already have ignition.

Replace the bucket and check if the pipe is good on the candle, if not, now replace the color may be dirty candles may be dirty or the candle break should be 0.6mm but I would not bury anything in your place replace the cable and how is it leave it like that

Circuit breaker contacts to be checked. I had such a fault that the chopper axle was wobbling and it was possible to drive only at high engine revolutions.

And are these supposed to be fully open or just to open? Because if I give all the gas, WSK only goes into gear after a while and not all of it as shown in the movies, it is so muddy, I think it is ignition. What do you think?

Mate1990 · Answer

Now I understand, I will check and write tomorrow.

I checked the break, it was 0.30 mm, I set 0.40 mm and you have to dig yourself in to speak. When it starts, I will add a little gas and it goes out. He smokes terribly. And there must be something on the plate that moves, can you file it? And there's a bit of a curve, they don't touch evenly. Or maybe it's a carburetor, this bevel bolt is tightened almost completely, and the other half a turn is unscrewed. It was like that before and she smoked well. I don't know what's going on anymore

Mate1990 · Answer

Tomorrow I will accelerate the ignition, i.e. move it to the left, it will probably be not much.

Mate1990 · Answer

Hello, after a few days, the weather was bad so I didn't fumble anything. Today I set the gap to 0.40 mm with a feeler gauge and ignited with a 3 mm caliper, before TDC, and a spark plug gap of 0.30 mm. She fired the arrow, turned into high speed right away, and went out. I noticed that the cable for the candle broke, from the frost surely and the pull, the spark is there, but not always. I ordered a set of platinum, a cable, a pipe, a candle, a capacitor, a coil. I will mention everything except the platinum. And the color of the spark, what does it depend on? Because for me it is bright, and it should probably be so bluish.

Mate1990 · Answer

Hello, I changed the cable and the capacitor lit the first time, it also reacts well to the gas, but after a while it goes out as if there was no spark current at times. As I wring the candles, I will light it up and you can do it around the clock, what is it?

Mate1990 · Answer

It's no, it doesn't move for me. Tomorrow I will change the coil because I have a new one and I will see, maybe it's a coil.

Added after 18 [hours] 56 [minutes]:

Hello, I replaced the coil and that was the cause of it all. Now it fires from the kick, immediately goes into rotation. One more thing - the air filter, when I put it on, it muddies it up, even when I put on a metal mesh, it's fine for a while and then it suffocates it, I don't know what to put there so that some muck doesn't fall, anyone has an idea?

Anonymous · Answer

The filter must be there. These grids are not very precise in relation to paper filters anyway. The air inlet is obstructed by something?

Mate1990 · Answer

No, I put on a cone filter, and the same moments later she's muddy. That's what I thought to break this filter and put only this mesh on the carburetor band, so that it does not clog the 2 holes that are in the carburetor, maybe something will come of it.

Why a non-original filter? After all, it was such a drawer with nets that the flies would not be caught. The paper filter would have to be large not to choke the engine.

Mate1990 · Answer

Because I put a narrow engine into the frame of the waking part 175 and there is a big difference between the carburetor and the opening for the filter, and no rubber fits there, the carburetor is higher and the opening for the filter is lower.
