First of all, I'm not all that comfortable taking the distributor off, that messes up the timing if you don't put it back on right, doesn't it? Second of all, I have to let it soak with pb blaster since the line is rusted to it. Third of all, I can advance it by pushing in the plunger. If it works when I turn it manually, would that mean that everything is clear and working right except the advance?
