The lawn mower gives a lot of noise - what could be the reason?

Question

Hello. I have such a question, what could be the reason why the lawnmower is sooooooiled? I fired it yesterday and she walked normally for a while, until suddenly she started to lose speed and choke until she went out. I waited for a while, I fired on the suction and it started to smoke terribly...

Hello, maybe at the beginning, clean, or replace the candles

raceman · Answer

Yeah, for sure it smokes the candles .. Please! Most likely it's because of the rings on the piston, take it apart and see.

Rings, not sealed simering (could have failed). It is difficult to determine the cause without undressing.

Please think carefully before writing anything. In this engine, if the oil seal is damaged, at most the oil will spill out, not a two-stroke cycle. The color of the smoke indicates oil burning, rings, in fact, it's almost a new engine. It looks like a Briggs engine, you say yours is similar, so I don't know what it really is. You did not sometimes turn the mower to the side, if so, the oil has poured into the carburetor and muffler through the pneumothorax.

It is the same mower as in the picture because it is from the same factory, the only difference is the plastic on the top and the engine, all the same.
I don't know, I have to look for a receipt somewhere because it is probably still under warranty because it was bought less than a year ago. It was not tilted.

Yesterday she still smoked on the choke and today, when I wanted to check if she smokes, she did not want to catch it at all.

However, I would check if the carburetor is flooded with oil.

Marian2010 · Answer

Carburetor checked, clean, no trace of oil.
The mower was not tilted, today it is used for the first time after winter. Any hint on what the worn rings might look like and what is the best way to get to them? I've never had a problem like this, so I didn't delve into it.

Is it that I don't want to fire it too fault rings? I checked the spark and it's fine.

It is possible that you have rubbed the engine after all.
No compression and therefore won't fire.
To find out, you would have to unscrew the head.
To check the rings, the entire engine must be disassembled, it is not possible to remove the cylinder itself.
There is not too much oil by chance.
If you do, place a picture of the finish in the cylinder.

Marian2010 · Answer

Compression is good because I checked with my finger and it is strong. I also checked the candles and it's ok.

Anonymous · Answer

The finger is not used to check compression, anyway there are strain reliefs in these engines. Only unscrewing the head can explain something. You do not check what I wrote about and you want help.

raceman · Answer

This is a mower, not a TDI engine. Disassembling it will take you max 20 minutes, which is actually less than writing here and waiting for an answer. We have written what to check, so please kindly check it first. What are there to say. The surface of the cylinder should be perfectly smooth without any scratches. Also the rings. Take photos if you are unsure and post them here.

gentlemen, think about what you write, a new mower with oil in the crankcase and you write about seizure, if the engine rotates or with worn rings, I suggest reading some technical literature, in these engines, until what I see is a low-valve engine, the pressure fluctuates in around 5 at. head deformation is a new gasket, the force of tightening the head is only 2.8 kgm because the head is made of shasmetal, and it choked because the cylinder is lying and the oil that remained in the cylinder for so long has also penetrated over the piston, so it drowned, if it is some problem is only and certainly in the fuel supply system and I propose to work out an air filter if it is made of a sponge, if it was not done after the season last year, because there may be a reason here. Regards

My friend condition2300 then virtually all mowers should muck because they have lying cylinders. The amount of oil that penetrates through the working rings will be burnt within a minute. The oil level is not at the cylinder if the oil quantity is correct and the mower is horizontal. There must be too much of it. A dirty filter is like an auxiliary choke is turned on and the mower only smokes on the suction so the filter is not a reason. Light smoke is oil burning, black smoke, carburetor or air filter problems. Never seen a worn out new mower? Today's ones, if they get into the bone well, can rub (scratches in the cylinder), even with oil. It is enough to overheat the aluminum cylinder. Your statement on a similar problem, have you changed your mind? Perhaps, by chance, someone had poured a mixture of fuel and oil into the tank instead of pure gasoline. It is different There was already such a case on the forum, it concerned a power generator.
