OK. Truck was running great. Let it sit for a couple of days and yesterday I put some new fuel line on it and changed the glow plug. Now it will fire up but die when any throttle is given to it unless I leave the igniter on it. Low end is set at about 2 1/2 turns out, idle is good, I'm thinking high end adjustment but just can't find the spot. Is there a round-about turns out adjustment to start with? Could this problem be something else? Glow plug glows right away plus I've tried 2 of them now. HELP...........
