 If the sprocket timing marks are aligned as shown in the manual, then you should be TDC on compression cycle on cylinder #1. When the crank goes one revolution to TDC exhaust, the cams will only have gone half way around, so the cam timing marks will not be aligned.

Do you have a can of "quick start" spray? It is available at auto parts stores. If your timing is set reasonably close to correct you should get something firing with this stuff. If not, then most likely your distributor is still not set up right. A timing light is the most reliable way to verify that the spark is occurring when it should.

If you do not trust the sprocket timing marks, I suppose you could verify the compression cycle by removing all the spark plugs except #1. Then if you hand crank the engine, it will be noticeably harder to turn as you approach TDC on the compression cycle for piston #1 due to the compressed air. Or if you electrically crank the engine, it will tend to continue going, stop and bounce back on the #1 compression cycle. All assuming that cylinder has good compression.
