Zündapp Combinette was tanken?
Hallo,
Ich habe eine Zündapp C50 Super Combinette (Mokick) Baujahr 1971, diese tankt 1/25 gerade. Ich versuche sie nun die ganze Zeit abzustimmen aber sie läuft nur okay wenn sie zu mager läuft (hat dann aber sehr wenig Kraft, Zündkerze viel zu weiß) fett läuft sie sehr schlecht und Braun kriege ich sie nicht. Sollte ich Mal 1/50 tanken, oder macht das den Motor kaputt auch wenn man es richtig abstimmt?
Folgende Teile verbaut:
BING 17mm Vergaser
Afgefeilter 16mm Ansaugstutzen (jetzt wahrscheinlich 17mm)
50ccm Tuning Zylinder
Relativ offener Luftfilter in einem Luftfilterkasten

Normal lead-free and 4% self-mixing oil.
In the case of 2-strokes, the vote is delicate. If you make changes, this requires a complete new tuning of the gasoline-air mixture. This means you have to cheer with different large nozzles and also place the slider needle higher or lower.
The manufacturers make hundreds of attempts to achieve the best setting for the original state.

I didn’t know that there were vehicles that could fuel themselves.
You’re writing a tuning cylinder. In addition, an open air filter influences the vacuum and thus the mixture composition. Has the carburetor been tuned to it? Is the ignition voltage okay?
Only if that is true and no improvement occurs can one think about another mixture.
Correction: I refuel it 1:25, the air filter is not original and looks very open (only one filter and that was, no extra plastic housing or the like) tune the carburetor? Tell me, I’m not a professional, do you mean the nozzle and the needle? The ignition has no problems.
Yes, nozzle(s?) and needle.
An air filter without the housing may bring less air passage because the air is not directed specifically to the filter. Tuning parts are already counterproductive.
How did you find that the spark is strong enough to completely ignite a richer mixture?
This is a rumprobing, to determine the appropriate combination of nozzles and needle under different load conditions.
I’d have the ignition system checked before.
I didn’t find it, but the engine was already completely overhauled and I’m going out of it that would have been noticed there, but I’m going to look again myself, the needle position I’ve changed very often just like the air, so far had only no nozzles there, only a large and a little smaller one, with both it doesn’t work well, I’ll get other
