Hi guys, I’ve been having a problem with my Piaggio two-stroke scooter for a long time, that it drives a little bit thin at full throttle. So I drive with 3/4 gas much faster than with full throttle. I actually dared to expand the carburettor and cleaned it up. I forgot to clean the nozzles with a needle at that point, however. Now after the dismantling did not do much. A little later the problem started with the strong amortizing again, until I yesterday on the A The scooter starts again after a while of cooling, but then only for a minute. So my first guess, to see on the picture the gas train doesn’t look quite healthy anymore, could that be the cause? Too much air? Since the problems have existed for a long time, I also have the impression that it’s something else. I would be very grateful if you could give me some tips. Piaggio Zip 2 clock 2003, 14200 km P.
