Hello dear motor talk ́ler, my parents bought a Piaggio Zip 50 4t from the dealer in 2007, 12 years ago. The scooter always ran problem-free. 2-3 years ago I drove it from time to time, I noticed that he really jumped at it, but needed a few meters until he really had the full performance. My parents then gave the thing to a relative before last year, that he could drive to work. This used it until the end of last year then also every day. Now he doesn’t need it anymore and gave it to me as a daily for errands etc. pp.. Now the story starts. I wanted to start it yesterday the first time, he stood from the end of last year until the day before yesterday in front of the house, without tarpaulin. Battery was still great, but he just didn’t want to go on. I am to Louis and they told me that there is a special spark plug installed, which we did not have in stock, a “ZUENDKERZE NGK PMR7A” for 32.99€ (Louis Link) I just have the a I turned out, see there, there was a “ZUENDKERZE NGK CR8EB” in it which looked not super bad at all. Louis Link Well, still changed and the thing filled brimfully (were almost 7L Super). In EasyParts it also says that a CR8EB is installed. Link Easyparts Despite the fact that he did not want to go on, not even with the kicker, a two times, in +30 attempts he started short for 3 seconds but straight out again. At the felt 100 ́st attempt he jumped. Lief le I gave about 5% gas and sprayed into the suction down WD40, then it ran better and from now on you could give about 40% gas, with this gas position I then rolled home. As soon as you had given more gas it was super dull and became very slower than that it got faster. Can you tell me what would be worth replacing ? Carburettor clean or directly buy a new ? Video link, in the middle one hears quite well, than i ch went from half to full throttle that flattened the power. Video link Greetings 🙂
