A stuck valve can cause low compression. If you check engine compression, I can point you in the right direcion. If I am wrong, then we need to check the timing. Since the car sat for so long, there is a chance that a few valves have stuck in the open position.
For directions on checking compression, visit our homepage under the DIY section. It isn't hard to do. You will need a compression gauge. Most parts stores will lend or rent them to you.
Let me know what you find. Also, if you can send a video and upload it for me to listen to, it may help.
