Some simple tests. Take the hood and valve cover off. Crank the engine over and watch the valve train for proper mechanical operation.

If you don't then valves are not properly set and there is no vacuum to pull the fuel through the carburetor. If this checks confirm proper timing and spark on #1 cylinder. Hold the spark plug grounding the nut of it to the engine and watch for spark when timing mark comes around tdc. If all this checks out shoot some wd40 in each cylinder and see it it pops off momentarily. If that is successful shoot some wd40 into the air intake on the carburetor while somebody cranks the engine. If it tries to run you are not getting fuel through the carb.
