Hello all, I got a ’96 Rex 50 2T from a friend. The scooter was 6 years old and I saw it as an opportunity to deal with it. I only screwed a car so far. So I read a lot, watched a lot of videos, changed battery, removed and cleaned carburetor, HD and ND cleaned, petrol filter renewed, air filter renewed. spark plug new. Gear oil also changed, but that’s by the way. 2T oil also refreshes. So, scooter starts again nice. If I think also quietly in idle for a 2Tacter. Until half-gas position it also runs well, then come to 35-40km/h. But as soon as I give more than half-gas the thrust is lost. Stutters not, but simply no acceleration at all, feels like idle and then I would just roll out. Then let go of the gas lever and return again until H This sounds like a fat mixture, doesn’t it? But I didn’t change anything about the screws on the carburettor. Air filter has also remained a standard model. Or false air, but wouldn’t it rather express itself by stuttering from half-gas? Can someone give me tips on how to proceed? I thought that too fat mixture could be either too much fuel or too little air. Could it be that the new carburettor could be too much air. Air filter leaves too little air? Could I just leave it out or does the carburetor have too much air anyway and only falsifies my further search? Thank you for your help.
