Thread: Engine wont spin?

Thanks for the advice. It was stored in an outdoor shed, definately not the best storage place since its still subject to humidity. I figured the cylinder walls may be rusty like you said. We'll try the wd40 trick tonight. Assuming the walls are indeed rusted (and worn), what is the approx cost for a bore/hone job? I think a few hundred? If so he should give me the motor for free!

Don't use WD40, use a real penetrating oil. Even diesel fuel works better than WD40. Pull the plugs. That'll probably show you which cylinder has moisture in it. If it won't free up with some prybar work, back the valve adjusters off so the valves are closed, and get yourself a pressure washer, make fittings to pressure up the cylinder with the washer, that almost always works!
