I bought a couple sentry valves for my brother's and my GOSM smokers. Tonight I tried to install it and am having some troubles. I replaced the burner and the regulator with ones from a turkey fryer as I had read. I got it all put together and fired it up. My problem is that is doesn't adjust at all. If I open up my needle valve all the way the flame goes way up and just stays there even when I set the sentry at 200 degrees. I shut the door and the temp just climbs up into the 500's. Anyone have any idea on this one?
