EnviroGard LPG Carburetor
There are throttle plates and 2 venturi's, one for each cylinder. If one Venturi has come out in such a short time it either was stripped during installation or was loose and can be reinserted. They must be properly installed for your engine to run properly. If you have had this for such a short time, why not send it back for it has a one year warranty. Let me know how I can help.
