Hey guys, maybe you can help me, thank you very much in advance! Before: Brand: Generic Motors Model: XOR (50ccm) Year of construction: 2009 Kilometer level: approx.6800 Km ___________________________ Sooo, the problem is that I recently installed a new cylinder + pistons, piston rings and all seals new. This went without problems, except for the fact that the old cylinder on the engine housing was slightly rusted, Zack rust solvers on it and left it overnight. Next morning almost fell off by itself. The installation of the new parts went without problems and was made quite fast. Also new installed, sport variomatics + clutch from Naraku. Now my problem, which the new cylinder was installed the scooter does not start any more, an equal 50cc cylinder was installed so one would not have to do anything at the coordination of my opinion. Ignition spark is there, fuel and oil arrives at the carburettor and also at the cylinder… Carburettor We have also tried to change the needle, hence less/lower gasifier needle but this without success, air filter is also clean and there we have also tried to change it. Information from the manufacturer for the coordination also does not work. Start remains without success. After several attempts we have removed the cylinder again, cleaned. Anyway the carburettor. We emptied the oil and petrol tank, cleaned and filled up with new liquids. I hope you can help me and the scooter will run LG again soon and thank you in advance Maurice ___________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________
