Hi from Phoenix AZ! Picked up a non-running 1974 Plymouth Valiant Scamp

Thanks, everyone! Good news!! I pulled the plugs, sprayed a little WD40 in there, pulled the starter and slooooowly turned the engine with a large screwdriver. It is free! I also stuck a borescope in each cylinder. Only one has a little surface rust. I also noticed the pistons are all stamped 30, which I'm assuming means the engine was rebuilt, bored .030" and got new pistons. I think I'll get some oil in the cylinders and slowly turn it over a few more times before I move onto getting a battery.
