Dito that, a pull start is a pain in the butt. Starter boxes are the way to go but get something decent with a powerfull motor preferably a single motor. Mantau has a great starter box (light waight and powerfull) and get a good starter battery (i.e GRAUPNER+CHARGER) which should set you back around $80. The Mantau starter box that I have also has a power panel so that I can use a glow plug atached to it and a pump for refueling. The power supply to the glow plug can be adjusted so that you get the right heat to your plug without over heating it.
