Yes my name is Darrin and I have a ryobi 31cc weed eater that when you prime the bulb to start the engine is spurting gas from the back of the carbuerator where there is a hole. I cannot figure out what the problem is can you please help.

Most weed trimmers have 2 fuel lines coming from the tank to the carb. Look for this, it sounds like the return line is missing. As for "Ryobi" brands I am not sure.

Also,mayby one of your fuel lines is cut or broken at the nipple connection.

All The Other Answers Sound Good, But Some Of The Carbs Are Coming Out With A "cap" Much Like To Older Vacuum Line Caps.

The diaphragm is most likely ruptured under that cover. The carb needs to have a kit put in it.

Ironhorse, that is a possibility, but some of the carbs do not have kits available, you have to replace SOME of the carbs completely. It would just depend on which carb he has.

I have to concede to mowerman2468, He is correct. I also missed that the return line might be broken or missing, as well as a cap. Yes, it's unfortunate the some carbs are not rebuildable, only replaceable. So many things are just throwaway today, and shop rates prohibit rebuild times, or parts are just not available. I will investigate the anti-afterfire solenoid being disconnected, and a no run condition happening. Thanks mowerman2468 for the input. Keeps Us on our toes comparing experience and knowhowand, ultimately the customer.
