Okay, here's the story. My dad's 80 RX has not been run in about 7 years. He tells me that up until that point, when he wasn't driving it very often, he would always run it once a week. Then it slowly became once a month, and eventually it never got run again. I'm trying to do a restoration and figure out where to start first. I tried turning the main pulley by hand, and it wouldn't budge. So I asked what the last running condition was that he knew of. He said that it was not carbon-locked, and ran beautifully. My suspicion is that there is some binding surface rust that siezed the rotors. So I'm wondering what I should do to get the rotors free again. Should I use ATF/MMO/power foam treatments? Should I use the rolling backwards down a hill and dump the clutch treatment? Or what else should I do to get it spinning?
Thanks a lot,
Evan Schmidt

Thanks, guys. I'll re-post with an update after I get a chance to work on the car.

the front and rear of the rotor surface will rust to the cast iron plates.

if the above doesn't work, spray some PB B'laster in the intake ports, exhaust ports, and spark plug holes. It is GREAT at dissolving rust. And is oil based and will lube surfaces it comes in contact with. As well as burn albeit smoky.

I'd turn her over by hand before using the starter.

You can get it at pretty much any auto parts store.
