Most wedeater and chainsaw carbs these days are diaphram type and do not really keep much fuel up in the carb like the older float bowl type still seen on many lawnmower engines. If you don’t have a priming bulb(best thing since sliced bread for small 2 stroke engines), you can try putting a little fuel/oil mix down the carb opening with the air filter removed to get it to fire initially and help get some fuel to be drawn up from the tank into the carb. The diaphram pump in the carb draws fuel up to the carb using energy from the pulsed airstream thru the carb.
