is it possible if I set the valves to tight would that cause more back presure out the vent tube?? I set them at .006 but I might be a fool and didnt get it quite right. although I think that I set them right
Not at all. If you have a lifted TXT, the engine is tilted to the rear and the dipstick is to the front. It's very easy to overfill the engine if you fill to the full mark of a lifted cart. I believe they hold 1.5 qts.
