I am using my Masterbuilt 30" propane smoker for the second time. The first time I used it, I was having issues getting the temp down to 225 when cooking in the Texas sun. I was told to buy the following needle valve. http://www.smokingmeatforums.com/t/128297/needle-valve-mod-using-bayou-classic-regulator I installed the needle valve, but my fire goes out every few minutes. I'm constantly having to relight the fire. Any ideas?
