I have a .18TZ and it will start on the starter box but it will only run for about 5 sec after i take it off the starter box. The same goes with the glow plug starter, as soon as I remove it the engine dies. What settings do i need to change? I have it set exactly as the manual stats, the needle is all the way out, the carb is open 1mm and the fuel setting is open 2 turns. Any ideas?
