If you don’t have fresh fuel in the tank, replace it. Try to borrow a working carb. Check the ground to the motor from the box and the ground that jumpers over the vibration mounts for the coil. Open both needle valves for the carb roughly a turn & a quarter. Try starting the motor without the air filter and a hand over the carb inlet. Crank it briefly. Should have some fuel spill out of the carb. If you’ve taken the carb off, did you pay attention to installing the gasket so it doesn’t block the pulse port in the block and the carb. good luck.
