I don't know if its me, my torque wrench or what. I have a new craftsman click type torque wrench. My book says to tighten the carb bolts down to 12 ft lbs. Well I do and they are so loose i can put a wrench on them and still tighten em down easily. I set it at 30 ft lbs and a week later they had loosened up. It wasn't until I tightened them to about 40 ft lbs that they feel good. My concern is that when I go to tighten down some head bolts the torque won't be adequate. Can you recommend a good torque wrench or something else?
