Start out with a full charge (overnight) on your ignitor, then install a new glow plug. Save the old one, you can use it later when it's tuned right.
Take off the air cleaner and look inside the carb. Don't try to start it yet, but turn on the radio and Rx. Turn the trim knob down to zero, then hold the trigger in maximum brake position and manually adjust the idle screw till you have an opening of 1-2 mm, or close to 1/16".
Prime the engine by plugging the exhaust while cranking it till fuel reaches the carb. Reinstall the air filter and start it normally and let me know what it does.
