The spring loaded thing under the carb is often the float bowl drain. If you, you should get fuel out when you depress it. If not, no fuel is getting to the carb (most of these are gravity feed, so it would be a plugged line or filter). Are you getting spark with the new plug?

If so, give it a shot of starting fluid and see if it fires....The electric starter takes some of the voltage going to the coil. Try the rope pull a few times.....
