Get a can of Kroil (

Roll the engine over by hand, or spin it with the starter after a few days of soaking, and make sure all the moving parts you can see are functioning properly.
The gas needs to go, all of it. I'd suggest removing the tank and getting it professionally cleaned. Do the initial startup from a clean container like an outboard motor tank or something similar. The most common problem with starting an engine that's been sitting for a time is gummed-up valve guides and bent pushrods, caused by varnish from stale gasoline. It might be an excellent idea to open up the carb and do a thorough cleaning job. A rebuild kit is cheap insurance. Clean or replace the ignition points and spark plugs check the timing and valve clearance, and fire it up! Don't be surprised if the water pump and/or the fuel pump develops a seep leak. Sometimes they dry up with a little running, sometimes they'll need to be replaced.
