Englisch info vergaser wanted

BVF and NKJ are different vergaser-types.
i think you have a NKJ.
what problem do you have with it?
Hauptdüse is a tiny part in the vergaser where the fuel comes through. the nadeldüse regulates the the amount of the fuel that comes through it when you are driving.
you must put the nadel in the 3rd position.

don't know what the vergaser and the other parts called in english

tappywappy: Did you clean the carburettor ? This should be the first step you do. Do it very carefully and exspecially take a look to the nozzles.

Zitat

BVF Zentral- Schwimmervergaser ; NKJ 122-4 ; Einstellung: Hauptdüse 55 Nadeldüse 210 ; Nadelstellung: 3

This means, you have to choose the main-nozzle in size 55 (0,55 mm) and the needle-nozzle in size 210.
On the needle inside the carburettor you can see 3 notches, you have to hang up the needle on notch 3.

I hope this will help you and the words I used had been translated correctly.

hi there,
Hauptdüse 55 means that the main nozzle is size 55. it´s the nozzle under the pin.

nadeldüse 210 means that the pin nozzle´s size is 210. it´s that one, where the pin slides trough.

Nadelstellung 3:
the pin has some gaps. there is a kind of double-disk plugged onto the pin. "stellung 3" says, under the disk, or under the lower leaf of the disk one gap is left empty, if u know what i mean.
so the pin is not in the upper position but one step lower.

i hope this helps you a bit.
