I'll see about getting a hone and some rings. What hone do you suggest? Also I tried acetone, didn't work to great. I was thinking about trying some muriatic acid but I know it can cause more rust if I don't use it right.
Yikes. Ok, take a deep breath. I think you're in a little over your head here.
With that amount of rust and crap on the cylinder walls, there's no way you're going to just clean it up and run it, not without a ton of blowby. If you do, your cylinder finish is going to be all off, who knows what kind of shape the rings will be in, and they won't seal well, meaning you'll have lower compression, lower power, and burn lots of oil.
Now to do things right, you need to remove the rods and pistons and clean up the bores, or just flat out throw in a new engine. Considering the unknown status of your cylinder heads, I think the most cost effective approach is going to be a junkyard engine. You're in the $150-300 neighborhood then. To do things right on this engine you're looking at that or more just in machine shop work.
If you're absolutely broke as fuck and have more time than money, your other option is a hone and go. Not guaranteed to be perfect, but it would probably work. Get a hone from the parts store ($40-100), hone the crap out of all the cylinders, and put new rings on all the pistons ($27-65 on rock auto.) That's got about a 75% chance of working.
But whatever you choose, dumping acid and trying to clean up the bore with rings isn't going to work. It's just going to be throwing time and money down the drain.
