Hello together, am with an older CPI Aragon GP (2T) a bit perplexed. The scooter stood about a year unmoved and should now be put into operation again. Because of the service life the petrol hoses were porous and the rubber nozzles on the air filter and suction nozzles were torn. So new hoses on it, new complete air filter and new air intake nozzle with membrane on it. The scooter now also starts and runs relatively calmly. so that it does not drain directly. So standing gas for me inconspicuously, however, if you go off and fully accelerate, the scooter almost goes off at about 6,000 revolutions. When I take away gas it catches itself again. Had the consideration that possibly carburettors spoiled, petrol tap defective or petrol filter. Carburettor cleaned, tap and filter replaced, but the same problem. Now I checked the candle and it is quite black with a light oily film. Means That somewhere false air is drawn? Ask me then only where, since the intake nozzle and the air filter are new, whereby the new air filter with the rubber nozzle is only relatively lascivious on the carburettor and can be pushed down relatively easily. Could this possibly be the problem?
