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 
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
