Moin moin, I once again… I gave my omi a new cylinder head gasket after it consumes water and smelled it in the balance tank for exhaust gas. As far as everything is nice, but now, after the change, it doesn’t start any more. The control times should fit, I checked that several times (all markings are correct), ignition spark also gets strong at all four candles and fuel also (you can smell it clearly). Compression is so on all four paws around the 14 bar. And by my discretion, I didn’t forget to clamp a plug again. Pingly as I am, I have all the plugs and their counterparts numbered… Now I’m at a loss for now. Maybe someone from you has a good idea? Thank you very much and thank you so much Kai
