Hortmasz BCD-52 Brushcutter: Excessive Fuel Consumption and Smoke Emission?

Hello,

Two weeks ago I bought a Hortmasz BCD-52 brushcutter (capacity 51.7 cc, 2 SUW), which was recommended to me by the seller in the store.
I have a question, is it normal for the scythe to smoke when cutting with a 10 cm-12 cm 1 liter / 60m2 grass?
Recently, I mowed about 300 m2 and the scythe burned over 4.5 liters of fuel.
In the store where I bought a scythe they say it's normal combustion.
I also wrote to the producer and see if they reply.

I think my friend gives something wrong (4.5 liters for 3 ares). I will give an example I mow 10 a scythe and 1.2-1.5 liters is enough for this and the knee grass mainly dandelions and other weeds tired with a fishing line. If the new scythe may have an increased dose at the time of arrival but rather not so.

In my eye it burned too much 30 times. My Oleo-mac scythe on a 0.6 liter tank mows over an hour with similar grass, but I will cut 1000m2 (10 ares) per hour.

Today, my father used this scythe to cut 37 meters by 3 meters and burned almost 2 liters of fuel. I went to talk to neighbors who have scythes from different companies and look for their burning. As I told them that on the aforementioned slope the scythe burned almost 2 liters, everyone was surprised because no one has such burning as in Hortmash.

Look in the manual should be the average fuel consumption per unit of time. If it is under warranty then advertise. It looks like a suction problem or just leaking fuel somewhere.

Do the neighbors have almost 3-horse scythes? I have Kawasaki 3KM and can also eat when you choke on gas until the end without need. When you operate with gas so as to maintain the rotation of the head, the combustion is much less.

I understand that the 2.7KM scythe will burn more than e.g. 1.5KM but read the answers above, I think Hortmasz smokes too much.
A 10-liter bubble is not enough to cut 1000m2. The scythe smokes more than most gasoline cars per 100 km.
I also tend to have a carburetor problem.

Hello,
Nevertheless, I think that this is not normal. I have a scythe with a large capacity (51 cm3) and a power of 2.9 hp and for mowing a quarter of a hectare (about 3-4 hours of work) I consume 2-3 liters, so in my opinion such combustion, even in the absence of skills, is too large.

I was on the site where the carburetor was replaced.
After replacing the scythe, it was checked and it turned out that the fuel tank (1 liter) lasts for about 15 minutes of mowing.
At the service point, they wonder why there is such a large combustion.
It was called to the producer who did not answer what the burning of the scythe was supposed to be because they did not have such information.

Added after 34 [minutes]:

I have a question, what do you think about the HECHT model 154 scythe?

Dude, you probably did not expect such an answer, but in my opinion, give up this type of invention and get something more reputable company. You will avoid wasting time on setting up topics such as this or on websites.
How big is your plot? Do you need a scythe with this power?
I did not mow this scythe, so it may be good at this price but the scythe is a purchase for years, so not only the purchase price but also spare parts are important. Try to find Hecht all spare parts for this (except carburetor). After entering the password "piston hecht" one page of results popped out and after entering "piston stihl" - 27 pages.
Saving on such equipment is deceptive, because you will pay less first, but later you will waste time and money on continuous visits to the site (the scythe does not work and the grass grows). The sum of the summary is that cheaper equipment will cost you as good as installments, and with decent equipment you will avoid stress and live a few months longer
By buying proven equipment and taking care of it properly, you will forget about visits to the site for a long time (unless for a fishing line or oil for the mixture).
Instead of this scythe, I would even prefer some Stihl or Husqvarna (or other similar brands), or possibly a new Oleo-Mac scythe.
However, this is my own opinion and of course you do not have to agree with it but, as I wrote above, before buying a specific model, first check the availability of spare parts and services that will want such a scythe, because sooner or later such will be required.

As for me, 2.5 - 3KM must be because weak machines make it a hassle. I think Kawasaki TH48 starts easily in the grass up to the strip and cuts down the regrowth of deciduous trees, I recommend.

For me, weight and rotational speed of the head are more important. Combustion depends on gas handling skills. If someone does not harm their hearing and opens the throttle to the maximum, the fuel will go into the atmosphere and the engine does not have to have more power than at 3/4 turns. I would still check the fuel tank vent in this fuel-eating monster.

Buddy Kwok,
that's why I asked about the plot. I have one 2ha and the other 0.25ha. Until the first one I can not imagine a scythe weaker than I have now, but the second plot, mowing regularly so as not to grow it, I calmly drove a 2-2.2KM scythe, so if my colleague Rafa.w has a small recreational plot, is it worth pushing the costs?

Offtopic: I wonder if a real 2 - 2.5KM scythe is in fact stronger than all those Chinese with 3KM power and more. Similarly to the power of Chinese audio equipment. After all, paper will accept everything

It's stronger. The merit of this are very good carburetors (brand carburetor costs more than the whole Chinese scythe) so that these engines spin over 10,000. rotation. These Chinese have a lower turnover there are 7,500 revolutions. where brand names have 13,000 each Chinese inventions do not have more than 3KM even though they write in the ads 5.5KM.
At one time, you could buy Chinese chainsaws / scythes on the original Walbro carburetor.

As for the recommended blackbird models, there is a special topic on the forum that I recommend looking for.

Gentlemen, I asked about this scythe Heht because it was offered to me by the seller.
I said I want to return the scythe because it smokes a lot. This was stated by the manufacturer himself and the shop where I bought the scythe.
Nobody knows what's wrong.
Generally, I see that the guy who sold me the scythe is trying to do something about it.
He called the producer just like me but there is practically no help.
He told me that the scythe manufacturer would not accept it but he could offer me a new Heht scythe for an extra charge, and he would take Hortmash from me.
Only these two companies have on offer, so the selection is not large.
I would also prefer to take money to add and buy e.g. Ole mac.

One quinol better than the other.

If this scythe, apart from combustion, meets the basic requirements, then I would take it to someone who really has an idea about the website. Because it is quinol like millions of others and it is hard for me to believe that this pipe cannot be unplugged
Because if one carburetor every 100 out of 100 is replaced by the same one, then it may not be really satisfactory

I am 3 years old from juli. It makes approx. 2 tmkw on the tank. A plot with a house 600m 4x platters with a finger ...
