April 27, 20215 yr I have a 08 Beta 125. Runs perfect... untill you put it nose down or nose up. It then changes idle and fouls a plug. Within a matter of seconds. Any ideas?

April 30, 20215 yr I think it has something to do with there being a breather hole in the float chamber, which lets neat fuel into the engine, when the angle of the carb is tilted forwards. Maybe this could be modified, or blocked up, but the float chamber still needs to be ventilated somehow. Edited April 30, 20215 yr by phiggs
