Hello forum, I think the title already betrays everything. I’m just not able to tune a carburettor cleanly. We have two 2T scooters in the family and every spring they bitch around. What really bugs me. (If the electrics were not so completely overpriced, I would have already separated myself) So every year I run into a workshop and every year I pay a few euros. But even more annoying is the effort, because every time that means that I have my scooter in di This can’t be rocket physics, can it? I didn’t change anything at the air mixing screw. Until he came into the garage in winter, he ran without mucking. The following is done because exactly the behavior described below has occurred after hibernation and freshly charged battery. Fuel new, carburetor (as every year) cleaned. Behavior of the scooter: Roller starts immediately. Turns then high up to approx. 4.000 UPM If the Choke acts, it goes down to approx. 1000 UPM at the speed. And then off, unless I pull off slightly on the gas train, then it chases immediately high to 4,000-6,000 UPM. It is almost impossible to hold the scooter to approx. 1,500 UPM with the gas train. If you start again (Choke is warm and out then), it goes immediately, eats between 2,000 and 1,000 about 1 minute and then goes out. With the idle screw, no stable UPM is achieved. If someone knows what to do then please explain to me, like a primary school student. Greetings Mischa
