Like I said the pilot will come on and stay on a little dancing to it with out the blower on then when then when the burner is turned on and gains momentum it blows it's self out. I can adjust what I think is o2 flow on a little rod under the gas valve and make it stay lit for about 5 min then it's done

If the pilot gets blown out when the blower comes on, I would suspect a problem with the heat exchanger. Call a local professional familiar with your furnace to have it checked. You could have a serious problem.
