The cord just goes in when the engine stalls, it isn't what is causing the stall. Most people, including myself, have this problem when first getting their X-Cellerator. It is just too rich. The excess fuel is cooling the glow plug causing it to stall. Try turning the low speed needle clockwise about 1/4 a turn. That should make it so the engine will stay running. From there, just follow the break in procedure in the manual.
