Servus (me again), I was on the road with the scooter for about 30 minutes. Once I got home, I thought I would turn off the engine immediately and look at the candle picture when it has cooled down a little. I did that and that’s how the spark plug looks like. (See photo) Then I screwed it back in again. This morning the scooter didn’t want to go to work. Angry, but good then just with my wife’s scooter. Now just try to turn it on. I made the candle out, it didn’t show a spark in the front at first glance. When I looked more closely, I see a spark overlay in the inside of the candle. (if you look in front) The candle is a quite fresh NGK B9ES for my Piaggio scooter NRG DT POWER. I drove about 150 km. Well thought what to do, there is still a new replacement candle. Previously tested, against mass and ignition spark is present at the top. This new candle inserted. Roll. It’s wet and smells like fuel. However, the wet is a bit of anthracite color? The spark is no longer in front of the new candle, but in the candle. Now I’m a bit perplexed? Setting carburettor, standing gas was made at the workshop 2 weeks ago. Since then it has been running well, except for the gas acceptance problems already mentioned in another thread when I drive over a pothole or a bumpy road. What could it be? che Kerze? CDI? (but changed) Ignition cable? (but changed) Air filter? (but changed) Carburettor is new and running. The scooter has been in the workshop 4 times for 2 years, because it has been drunk or turned up again and then is drunk and can not be started after that. So I am constantly pushing home at the scooter, about 600 euros poorer, but the scooter still has a problem.
