Constantly tearing the starter on a chainsaw

Topics / Questions
Added 27 comments
Already put the third starter on a chainsaw. The first was plastic, it was torn to pieces. The second aluminum - vomited the center. Now, again, I have already bought a third, plastic, while still just breaking the rope.



I consider early ignition a problem, since a break occurs either at startup or when the engine is turned off. That is, he makes a revolution in the opposite direction.

The starter itself does not catch the rotor, it is checked 100%, threw washers under the cover, grinded out excess on the rotor, etc.

The problem is that the ignition is not regulated, it has nowhere to move ... the gap between the millimeter body is one and a half force, will it be enough ... What is easier to do?

I don’t remember, well, it was with a small tire ... light. My current 8 kg)) Instead of a dumbbell.

It’s still a lot of weight for 2.2 kV


Another trendy habit has appeared - to remove the suction button. Without it, the start was disgusting. They don’t even put it on huskvarna. And so pumped up, snort and went.

Yes, I don’t know, I have a bunch of them left stretched, I shortened them and right now three chains. I use as a blunt. By the way, I bought chains of Calm store, it is written on them, calm, and tins simply stretch ... But the teeth are strong.

Yes, it’s true, at least twice it makes sense to change the rings. First, the rings are erased, then the cylinder. Pistons do not wear out at all if there is no overheating. IMHO. Well, it’s better of course a new one if there is extra money.

Easy and trouble-free

I don’t know about trouble-free, but I can’t call the Partner "easy". Somehow I had to cut someone else's - I immediately felt that it was more bulky and heavier than the "Calm" ...
Now they somehow disappeared from us ... I have not seen it on sale for a long time. And earlier we only had that “Husqvarna”, “Calm” and “Partner” ... There were no others ... (I chose the middle one. And inexpensive, unlike Husqvarna, and easier than the Partner)
And now, “Makits” have appeared, and some “Chinese” are on sale ... (I mean an unknown brand of saw for $ 100).

Horror ... I somehow did not think that marriage could be ... I have an old Calm-180. He is about 15 years old ... Changed the candles. I changed tires several times (they were erased to "foil)). I changed the drive sprocket (It’s my own fault - cut nefig with extended chains))). I changed the piston.
But this is planned wear. But so that such damage? !!!
And how many chains did your "cut"?

I had this, the first chainsaw. I miss ... The motor there is a fairy tale. I don’t remember the model exactly. It was easy and trouble-free. Here, too, I am looking for a partner, though I think they are not the same. That was bought 9 years ago.

Dmitrij,
I have a partner. Made in China, a branch of Huskavarna. What is interesting on the saw itself is the Huskavarna nameplate. It works fine for now. Already 4 years.

And the saws on these motors do different ...





In Chinese cheap copies of calm, such engines are also

no, these are chainsaw engines. They are very sophisticated. There is a crankcase of two side halves, the cylinder is attached separately. A sophisticated carburetor pipe and a bunch of everything that quickly breaks.

Ahhh, forgot to say. Do not believe me, but recently I went to the engine from an oil tank !!! xaxa Dumyar was like a tractor driving. I am at a loss, I open the oil tank - empty. I turn out the candle, turn the engine over, and oil and gasoline flow from there. By the way, after such an amount of mining, she did not bend ...))

It turns out there is a crankcase and a tank with oil separates the crankcase gasket, which pierced.

Gypsies .. theirs)) It cost very little, 800 UAH, how many rubles, I won’t say. Now they ask for her 2000+ UAH. I bought for the season ... forgot to throw it out :(

easy start yes, it was ... but it breaks very quickly. There, the movement is transmitted to the engine through the spring, this spring breaks constantly. If it does not vomit from the groove, then the metal itself will crack.

And you didn’t buy it from gypsies? My friend bought from gypsies, of the advantages of "easy start" all the rest are disadvantages))))

Squeezed out the crankcase seals, changed, turned up for fixing

The engine is self-disassembling. First squeezed the gasket between the halves of the crankcase. Well, I think, okay, it happens, I replaced it, I tightened it all well. After a while, everything repeated, the screws were loosened themselves. I collected the halves on the sealant. Under all screws he put a grover.
By the way, the cylinder was also unscrewed))

Redid the ignition ...

Twice I changed the starter ... By the way, in the very first native, the spring clung to the body with a hook, which was bent at all in the wrong direction. As a result, the spring vomited.

Gas tank breather did not work

Disgusting chain, literally from aluminum

Constantly flowing oil from the oil pump (during storage)

Broke the handle (made of a very thin aluminum tube)

Did not hold the air filter

At the last analysis, I found a longitudinal crack on the piston skirt. From where, it is not clear ... A piston pin hangs (although there may be a bearing, then it is not critical)

Heavy and gluttonous.

I am talking about the family drank 4500-5200 as a whole. Do not buy this nonsense. These saws are assembled under different brands. A friend bought the same, which allegedly made in Germany, but in fact the problems are the same, the motor is exactly the same.

I solved the problem. He took off the coil and sharpened the threads on the screws along the thickness of the coil.Now you can move the coil 1-1.5 mm. Also increased the gap between the magnet.

By the way, the clearance in the candle greatly affects the ignition timing. The larger the gap, the later the spark.

Well here, not only magnets can be biased. For example, a drunk Chinese turner has slightly shifted the groove on the shaft)))) or the groove on the flywheel. In the same place, a shaft is connected with a flywheel with a key. Or maybe the key licked a little and the flywheel has shifted, although it is unlikely but what does not happen.

it is necessary to move the coil counterclockwise, and there is a millimeter. Well, I'll try of course.
Magnets, if displaced, are from the factory. Can we increase the gap? So then probably the spark will be weaker.

Maybe the gap on the electrodes is not the same? The larger the gap, the later the spark. I will try to increase. Only start dumb ((

That is not, yesterday's exception. I just jammed not with a button, but with a wire, a short to ground. There was bad contact. In general, at first he almost drowned out, and then the contact was broken and she started up again, but she started up the other way and banged on the starter, breaking the rope.

There are no problems in draft, it works fine. At the start-up, the compression is noticeable ... There were no pops in the carb, but in principle they can’t be in the duetactor, since the window only opens into the crankcase. And with enormous wear, it would hardly have wound up.

Well, maybe I’ll take off my cylinder and see. Although she would have been poorly jammed. It happened to me on a car, turn off the ignition, and the engine on one or two cylinders continues to work.

from where on a cold saw red-hot deposits?

The first flash can create it, and the second can hit the reverse ...

or when turning off the engine. That is, he makes a revolution in the opposite direction.

That's what bothers me that guilt is an early ignition ... After all, it cannot be either early or late when it is completely turned off ...)))
That is, the reason you need to look somewhere nearby))))
Is the piston and crankshaft wear strong? Starts up well? Maybe everything is already hanging out there? Maybe the piston fuel mixture just flares up? There was no clap in the air, for example?

In the bottom photo, black bullshit is the ignition (as I understand it) + a magnet or two on the flywheel. Most likely the magnets are biased. Well they stick there or rivet. The coil itself is unlikely. Judging by the photo there are riveted on the template. What if you take a flywheel for a test in the workshop on bail? From the old saw. Or, as an option, try to make a plate and already attach a coil to it. But there may not converge in height.

from where on a cold saw red-hot deposits? You take absolutely cold, you start to tug on the starter, then bang, there is no rope ... Or it’s cracking with your finger

Big soot on the piston ??? In a push-pull, this can happen - gasoline explodes from a red-hot deposit, "not waiting" for a spark ...

it isn’t, so it would start without ignition and not jam

Those. Does it detonate at you? Maybe this is not ignition, but nutrition? Bad or wrong gasoline or carb is not adjusted.
