- No, no, no! Desperation ROT!

Hello to allle

So I have the following problem:

I have broken up my fat around the toe strap and everything that belongs to it renewed and also a lot more that seemed a bit strange to me.
All OT settings fit
1 cylinder bench OT ( OK )
2 cylinder bench OT ( OK )
Flywheel crankshaft OT ( OK )
After all this everything is carefully assembled again and again and again embarrassingly paid attention that also nothing goes wrong.
Water filled up and started carefully, and then it came, it no longer starts.
What did I do wrong?????????
Spark plugs unscrewed and controlled, see there no spark.
Then with Rainer Hüring, Frank Konnopasch, and also with Thomas Müller in connection, got a lot of help from them, but my problem is still there, no spark of ignition.
Hallgeber by Rainer worried, no change
All safeguards checked for passage, no change
(OT-giver was renewed last year).
I pull the ignition cable out of the distributor's finger and hold it to the ground and the engine is started I have NO CUSTOMERS.
It is not possible to read out because I don't have a tester and I don't think there is anyone near me who might be able to help me.
I thank you
Rainer who helped me with e.Teilen
Thomas who wrote me eMail`s
Frank, who's stood by me by the phone

Ask for more help as I only have my fat one, and it's been broken for over two weeks
You can also call me by phone o. email, I am grateful for any help.
