Run a fuel line from the pump to a gas can with brand new fresh gas. You can add all the stabilizer you want but bad gas is bad gas, you can't change that. Make sure you have the wires on right. Do you know which way the rotor turns? Here's a diagram to help make sure the ignition is set up correctly.
If it is all set up right and you're feeding it fresh gas, then just advance the timing a little bit at a time until it fires. Also, make sure all the plugs are in good shape, not cracked, fouled, etc... Make sure you don't have any rockers tightened too tight and holding a valve open. Let me know how it goes.
