Hi ! Welcome to IRV2! We're sure glad you joined the gang!
You may need to clean the burner tube and orifice. Remove the tube w/orifice and soak it in 91% alcohol for several hours. Then blow it out with compressed air, but be SURE you do not use high-pressure as you will destroy the orifice! I would keep it to maybe 30-40 PSI. Have fun and keep her between the ditches!
Good luck, happy trails, and God bless!
