Each time we think we have them set right it moves and we can not start the car. I am ready to burn the car.
Do you have all of the spark plugs out??? You may be fighting against the compression of the engine- what I mean is you have at least 2 cylinders with closed valves and the closed space is pushing against the piston which causes the crank to move. How much off does it move??? Does it jump a tooth???
