Why is my generator backfiring when I try to start it?

Your generator has a choke valve for stopping air intake before starting the engine. If the valve is open, your generator’s combustion engine won’t get enough fuel to ignite, leading to backfiring and the engine not starting. Close the choke before starting the generator, then open it once the generator is running.
