I hear the gas pressure when unscrewing the bottle, I tried poking the holes and hit it with a wrench , spayed with brack cleaner, and sprayed it in the carb, it would run off of that (jiffy rep told me to do all the above) I dont smell any leaks. I brought it in the house tonight to let it warm up. The only thing i can think of is some oil or something else in the new line.
