Hello first of all, I am aware that there are already many entries and suggestions for solutions on this topic, but unfortunately it’s not so easy for me… and since I’ve been making around the damn scooter for half a year now, I hope that you might know a solution. And I have had a Rex scooter since the end of last year. I got this one for 20€ because it didn’t run. Turns out that there was simply water in the tank (why ever) and jerk back Then I had a few problems with the spray drive, but also I gradually got to grips with it. After I drove the part a little bit, he suddenly had problems in the cold condition. Meaning: in the morning he did not get into the pötte and only after about 500 meters there were regular speeds in it. That was also always worse. So carburettor was removed and membrane as well as E-Choke made new. Didn’t do anything, well, now he just runs 30, but the suit is ok until then. Here’s a list of all the things I tried or did: -New membrane -New E-Choke -New intake nozzle -New air filter -New fuel filter etc. (Completely tested up to carburettor) -New CDI(must I make extra on the wire harness…) -Carburettor set, all possible settings tried through -Ventile set. Nevertheless, nothing continues, and these 30kmh are really not acceptable, especially since he sometimes I hope you can help me. Thank you in advance. Greetings Lars
