Simson s51 problem (HELP)

  • Hello everyone. I'm sorry for speaking English but I have a simson s51 comfort and iv a problem with her.. it takes a long time to start but will happily run but when I turn it off it will not start again X( she also stops running a lot and cuts out and struggles to start.
    Iv fitted new stator coil/ new condensor/ new spark plug HT lead coil.

    Ignition timing is good and points gap is good. Please help I'm struggling :unsure: :unsure:

    Here is a video of the issue cutting out

  • He's saying it's an comfort, means 6V or 12V electronic ignition normally.
    I don't think it's his original ignition cause of the contact and such gizmo.
    Firstly I would check your shaft seals, better buy some new,
    20x47x07 (Ignition)
    20x30x07 (Sprocket Chain)
    22x35x07 (Shifter)
    20x30x07 (Clutch)

    Don't forget some new oil, clutch gasket and mostly time.
    I would consider to clean the carburetor, should be a BVF 16N1-11 or 16N3-4, check the jet sizes for correctness.
    Your ignition needs 1,8mm before dead end.
    Where are you from?
    Not everywhere are the best parts available like here in Germany.
