NOW THAT I HAVE THE PARTS FOR REPAIRING MARX 333-PLEASE TELL ME WHERE I CAN GET

instructions for replacing the headlight on the 333 without damaging something. If there is a link to how to repair marx euipmentr that would be nice, but I really just want to replace headlight now, or when it comes! Now the 333 is a non-smoking engine right? or should I try dripping a little 3inone oil down the smokestack? Just kidding!! Thanks for all your help!!
