    It seems like it’s not getting enough fuel. Are you leaving the choke partially on after it starts? Initial settings on the mixture needles are 1 1/4 turn out on the slow speed needle and about 1/3 turn out on the high speed needle after being gently seated. Opening both of them a bit more to richen the mixture won’t hurt anything as you’ll be adjusting them as soon as the motor starts. It’s all explained in the owners manual I’ve attached.

    If the tank is nearly empty, it might require additional pumping on the tank button until enough pressure is built up in it to supply fuel to the carb. Not so much with a full tank.
