Hello together, I have (would like to write “drive”, but most of the time it doesn’t work…) a Piaggio Sfera 50 NSL from ’93. Unfortunately, the mopped usually doesn’t start… But a little indiscriminately. As an example the current situation: I tried to start the scooter 1 1/2 weeks ago. Starter goes, rumbles constantly, but scooter doesn’t start. Then I ordered a new e-choke because it is one of the last parts I haven’t changed yet. Then I am today to the scooter to install the, think “oh, testest again short”, starter pressed and scooter starts immediately, without murmuring. Hmm. No matter, new E Choke is there and will not hurt, so new E Choke will be installed. Battery on it, starter pressed, mopped starts, everything well. Briefly away from the mopped, other screwdriver fetch, wanted to adjust the carburetor because he somehow turned quite high with the new E Choke in idle, push the starter and nix. Starter roll, but planer jump t not on! On situation before he didn’t jump again 1 1/2 weeks ago: Before I got him, but always only with gas giving when starting and the first minutes I always had to give some gas in the stand so that he didn’t go out. If he was then warm, he ran but ok, was always rather high at turning in the stand, which is why I didn’t want to make the idle drah number höhher so that he would have stayed in the cold condition even without gas. Interestingly, he ran this morning , when I hit him the first time after he stood for 1 1/2 weeks, immediately without gas. I had the phenomenon already that he suddenly no longer sprang up and when I then wanted to pick him up a few days later he immediately jumped on without murmuring, since then he ran as described above, somewhat grumpy at the beginning but when he went warm. What did I do/what is new about the scooter so far: – carburetor cleaned – new air filter – new exhaust and crackers – new spark plug – new E Choke What can that be? Does someone think of something? I don’t know what I could do now… I attached a picture of the spark plug of today. Thanks already and many greetings rouvinski
