I have a O.S. .61 FX with the needle in the upright position, like on this [link=http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXLL61&P=0].65 LA[/link]. Since the engine is mounted sideways, it would be more convienient to have the needle valve mounted sideways like in this [link=http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXBY46&P=0].61 FX[/link]. My question is, how can I change the position from upright to sideways on a .61 FX? Thanks for your time
