My moped keeps stalling. What can I do?
I've already found some information about this question but haven't found a proper answer yet. I recently fitted a new spark plug to my Ciao Px as my moped did about 45 km/h and I've heard that there are different spark plugs for different speeds. I've now fitted the NGK B7HS as it's designed for 50 km/h. I've also fitted the Malossi air filter. The moped ran perfectly for a week but suddenly it won't start properly and when it does, it runs for a very short time and then slowly dies again. I've already increased the idle speed but it only revs up briefly and then slowly dies again. At higher speeds it runs smoothly but as soon as I slow down again it automatically stalls. If I press the choke and accelerate for long enough, it only accelerates above 20 km/h and then dies. Before that I have to drive for what feels like half a kilometer before anything happens. What could be the cause of this?

Can have different reasons. Carburetor needle wrong, mixture too fat or too thin. Or spark plug wrong. In these, the so-called heat value depends.
It’s not the Mofa, my Mofa, but the Mofa, my Mofa.
B7H(S) is the right spark plug! Alernativ also goes B6H(S). It cannot lie on the needle because the Ciao is equipped with flat slide gasifiers! I’m just trying to determine this with the mixture via the nozzles and gasifier size as well as the air filter!
Who the engine is first up and then slowly goes down at the speed.
Is always a sign that either the nozzle is not properly free,or it draws somewhere wrong air.
On the other hand, there is no candle for more speed or slow speed.
The heat value simply regulates optimal combustion and optimal temperature in the combustion chamber,
If you change the heat value, it can result in unclean combustion, and even overheating in the cylinder and damage in the engine.
Please clean the provided candle and check with brake cleaner when running the engine if air is pulled somewhere wrong.
Zb, suction connection to the cylinder,or gas for suction.
Greeting
At the Ciao you can drive both B6H(S) and B7H(S)! At the 6er candle, the candle picture is slightly darker than at the 7er! The B7’s going to be great at my Ciao! And that’s 5000 km! Candle painting is shiny brown! Yes good at my Ciao is the combustion air ratio also calculator Lambda = 0.96, so something to fat but well….runs! If, according to his information, the questioner drives Malossifilter with Dell’Orto SHA 13/13, he would have to drive about nozzle size 66!
Who you say it will be right.
I only know that you drive with a 14 ASS original with a 54 nozzle.
Speaking of:the heat value of the candle,is given by the candle and moped manufacturer and most accurate examined.
Just because your moped is running with it,not that it is optimal for late to follow.
Zb,deposits,or ignition glow,Folge=colds extinguisher
But no matter what, in 10 years there is more about this matter.
My Ciao is freezing, so I drive a colder candle, I don’t want to have another hole in the piston floor!
Young boy😂 do you know what you’re going to do?
At a ngk this is so…
High value=cold candle,hot combustion
Low value=hot candle,cold combustion.
Bosch vice versa.
How was that again?with the 7some she runs better and gives no hole?😂😂😂😂😂
The heat value of the candle has no influence on the combustion at all….the combustion temperature will always buzz around the 2000 degrees Celsius! It was just that the 5s could not dissipate the heat enough and then soo hot became the one hole in the piston and the candle was also melted! The 7er is a colder candle, better directs the temperature to the cyli head and so the engine interior does not melt away again
That’s how 2000Grad?then your cylinder would be fused.
Of course, the heat value of the candle indicates the combustion temperature.
As a rule, maximum Ca,800 degrees should prevail depending on the engine.
In addition, an annealing can occur.
But one thing you’re right, Light Candle directs the heat from the inner to the cylinder.
The rest is not what you’re doing.
Read here.before you write such a measure.
I’m sitting laughing and laughing at the table.
In the topic “Base”
https://de.m.wikipedia.org/wiki/Zündkerze
Quote Wikipedia: “In the case of a short insulator foot, the heat can be delivered quickly via the thread to the cooled cylinder head. This is a “cold” candle with a low heat value. This is used for high-stressed engines.” And the NGK 7er is a cold candle! The combustion temperature is approx. 2000 degrees Celsius! I’m talking about the combustion temperature that is reached in the flame front! With the max. 800 degrees, you mean the temperature of the spark plug, this should not exceed 850 degrees C!
Jonas.
No 800Grad is meant to burn, please read it again.
At 2000Grad, your engine will melt.
Yes exactly cold candle=heise combustion and vice versa.
Or send me a link to the 2000Grad
Otherwise, please learn
Quote: ” Now the combustion begins at the petrol engine, the necessary spark comes from the spark plug (fire ignition). During this process, the temperature rises to about 2000° C. Now the piston is pressed back in the engine and the combustion ends by the expansion (working cycle). In the diesel engine, the self-ignition capability of the diesel fuel is utilized at the prevailing high pressure (self-ignition). Here, too, the combustion temperature is about 2000° C., as a result of which the piston is also pressed downwards and thus the working cycle takes place.”
My God, I don’t believe it all….
Somehow are consulting-resistant, aren’t they?who told you this…..?
No motor holds 2000Grad.over 800Grad(approximately) it even gives a glow ignition that leads to a piston or cylinder damage.
And this is already the top limit.The average value at 2 tacter will be at 400-500 degrees, depending on the candle,heat worth.
Or, as already mentioned, send me a link.
My goodness I’m talking about the combustion temperature, NOT the temperature of the engine itself! In the flame of combustion up to 2000 degrees are achieved! In the 4-stroke petrol engine, even the exhaust gases are partly 1000 degrees hot (e.g. elbow glows etc.) I only talk about the temperature that is reached in the flame during combustion! https://de.m.wikibooks.org/wiki/Motoren_aus_technical_Sicht/_Ververgleich_between_dem_Otto-_and_dem_Dieselmotorr
What carburetor?? Nozzle size? What air filter?
