Just finished a Texas hog ham and front shoulder in my smoker. Had a hard time getting it to 160+ took along time. Started at 190 200 0n the temp gauge. ( don't know how accurate it is) Finished it off for about 3 hrs. at high. Total time 8 hrs plus. The interal reading barely 160? Any idea's? I did wrap them in foil and put them in the oven for about 45 minutes to make sure got 170 . Electric smoker?
