Just remember there are three things you need to get an engine to run: fuel, air, spark. If any one of those is not present then it won't run. Does it have fresh fuel? Does the carb deliver fuel to the combustion chamber? Is the float in the carb stuck? Is the air filter clean? are there any air leaks around the carb or combustion chamber? Are your spark plugs good? Are they properly gapped? Are the plug wires cracked or otherwise deteriorated? How is your cylinder compression?
If you replaced a lifter, how is you timing? If your valves are opening at the wrong time then there will be no compression, and therefore no combustion.
