Hey folks... I currently have a MB propane smoker. I did my first smoke this past weekend and the temps were all over the place. I didn't adjust anything and left the vents the same just to see the range of fluctuation...it would be as low as 205 and then as high as 245 within 15-20 minutes. Wind was hardly an issue, so I hope the needle valve will help. Any other suggestions to help regulate the temp would be much appreciated! Here is my smoker: http://www.homedepot.com/p/Masterbuilt-Pro-Dual-Fuel-Smoker-20050412/202904343 Anyway...I've read quite a few threads on needle valves and the one that keeps coming up is this: I understand that I will need to buy extra fittings, and that's okay with me. Here's my main question... Is it okay if I install this at the end of the propane hose and before the nob that is already on the smoker? I read a comment before that said if I put it on before the nob it won't make a difference because the nob still regulates all of the propane. Also...should I use tape at all of the threads? I've done quite a bit of plumbing jobs around the house and around pools...so I feel fairly confident...but I want to make sure I build it so it's safe and so that it works properly. Thanks for any/all advice!
