Can anyone tell me how to trim this engine? My accelleration pump doesn´t seem to function- have no description how to trim it, when I give full throttle, the pump moves slitely, ca 1mm and it stays down (that can´t be OK, can it?? It still ca be pressed down 6- 8 mm. My dealer in Norway doesn´t seem to know about this; and neither does the local Jawa- dealer.
