I have been working with Husgwarna 128R for seven seasons on hay making. The volume of work is approximately 2-3 hectares per year. The positive side of this lawn mower: it is the design of the clutch, just like in a chainsaw. Allows re-gasing during mowing (gas discharge when retracted). For seven years, the circular spring has stretched a little and the inclusion occurs at lower speeds, but this does not affect work and safety. The most important thing is never to burst or jam the clutch (unlike Chinese ones). Unmatched efficiency per hectare does not take more than 10 liters of AI92 and depends only on the density of the grass and the correctly selected disc. Reliability speaks for itself. 7 seasons without repairs. Even the candle and with which it was sold. The shape of the casing and its location to the disc ensures that the grass is laid in the swath when the handle is correctly adjusted and attached to the knapsack harness. Ergonomics and lightness make work a pleasure. Carburetor adjustment is simple and straightforward. When mowing lawns, three-blade discs with pointed blades with a diameter of 255 to 360 mm are excellent (the size is taken depending on the evenness of the lawn surface). At the same time, the quality and performance are NOT comparable to the work of a fishing line. Disadvantages: Attaching the handlebar grip to the Barbell will cause it to be redone right away. Does not hold, when heavy, the thread breaks. I drilled holes through and bolted them, but this season I replaced them with a calm one. The supplied disc Gross 255-4 is not worth using on all herbs. Exclusively only on heavy ones. Thick, dense and tall grass. On light grasses, he begins, like a flywheel, to spin the KO braid of unnecessary revolutions. But there is not a word about this in the instructions. Well, there is one more thing this is the growth of the mower, its maximum height is 180-182 cm.With more, it grows and with correct adjustment you will warm up back with a motor, or you will NOT be able to adjust the correct blade angle at all. Line cutting with this braid is NOT impressive. When working with a knife on a lawn, the effect is many times better, but to reduce the cutting height on flat lawns, instead of the native support cup, I put a smaller one from the Chinese lawn mowers. Well, actually, all the disadvantages.
Great machine. Once started to stall, but cleaning the flame carrier fixed everything.

Husqvarna 128r carburetor adjustment
The first question worth answering is the title topic overview. Why is it necessary to adjust the carburetor of the 128th scythe? It’s all about European fuel standards. The 128R is tuned to EU fuel standards. We have lower quality fuel (we are discussing AI-92 gasoline), which necessitates this adjustment.
The adjustment procedure for the Husqvarna 128R carburetor is NOT complicated. What do you need for its production. RPM tachometer, adjusting screwdriver.
1. We set the line out of the trimmer head 15 cm long on each side (this significantly affects the speed).
2. We dilute AI-92 gasoline with Husqvarna engine oil for two-stroke engines in a ratio of 1:50 (one part oil to 50 parts gasoline). For ease of calculation, we recommend the ratio. For 1 liter of fuel x 20 milliliters of oil. For the first start of the streamer, we recommend a ratio of 1 liter of fuel x 23 milliliters of oil (ratio for engine break-in). Strict adherence to these ratios and the use of only Husqvarna two-stroke oils is the key to long engine life and the supplier’s warranty in the event of a warranty claim.
3. We launch the scythe and output it with the throttle stick to maximum
Turnovers. The right adjusting screw H adjusts the speed to 8500.8800 by tachometer.
4. I release the throttle stick. At idle, on top of the carburetor, using the adjusting screw T, the idle speed is brought to the level of 3000. 3200 by the tachometer. At the same time, the motor should run smoothly, without jerking. The trimmer head must stop turning.
5. In case of visible smoke from the exhaust gases or erratic idling at the set idle speed. We regulate “mix quality” left carburetor adjusting screw L.

Husqvarna 125R carburetor tuning without tachometer (workaround)
How to adjust the carburetor, if it is necessary to work, and service with a tachometer is far away.
We run over to the main working part of the tool.
Cover the working part with a protective cover.
Despite the fact that an iron disc for grass is included with the trimmer, in addition to the trimmer head, I prefer to mow with the trimmer head, fishing line.
To extend the fishing line to the desired length, you need to press the blue button and pull out the fishing line.
Changing the line is NOT difficult. To do this, you need to press on the 2 latches on the sides of the disk and drown them a little.
. Remove the head body.
. And change the line. Back housing slips right into a click.
If you accidentally stretched the fishing line to a great length, it’s okay: there is a knife on the body of the protective casing, which, at the first revolutions of the engine, will cut off excess fishing line.
Let’s continue. To hang the trimmer on the harness, on the bar, in a comfortable place, a loop is attached. Adjustment of its position can be carried out in place, after putting on the ammunition.
The lawn mower is NOT capable of long-term operation. The gearbox and engine will overheat. Mowing is an option for less than 15 = 20 minutes, taking a five minute break. On a hot afternoon, working hours are cut in half. When mowing weeds, sedges, the working time must be reduced.
If the launch fails, we start to find the reason for the failure:
- Check the quality of fuel;
- Make sure that the candle is working and the candle channel is clean;
- Check the cleanliness of the air filter;
- Make sure the fuel filter is not clogged;
- Check the cleanliness of the breather;
- Cleans the outlet.

Such reasons include clogging of the internal channels of the carburetor, wear of the gasket here and a violation of the density of the internal Holloway with a loss of vacuum. Repairing lawn mowers at home, if it won’t start, will take patience.
The fuel mixture is suitable prepared with strict observance of the proportions of gasoline and oil. With all this, you can not use another brand of fuel. To exclude the ingress of dirt, gasoline must settle in glass or iron containers for 4.5 days. Do not use plastic utensils for storing fuel. Accurately measure the oil with a syringe without a needle. Use only freshly prepared consistency. Do NOT leave used fuel in the tank. If the engine is picky, the lawn mower stalls, when you press the gas, you are guilty of fuel.
The lawn mower does not start on hot. Pull the gas trigger and sharply pull the cord a couple of times until the engine starts, then pull the trigger later. Does not start. Special repair required.
