If the float is stuck then the carb will overflow as you pump the primer, which would never get firm. If it is firm, then the needle is working, or there is a bad blockage in the carb. On a functioning system, the primer will get firm when the carb is full and the needle closes off the passage, and stay that way as long as the engine is running.Chances are there was junk in the carb bowl, and it has now sucked some up and plugged the jets. It'll need to be taken off and gone through. You can also give it a little prime of premix, carb cleaner, whatever down the throat, see if it pops, to confirm that it is lacking fuel.If your spark tester is one of those with the little light bulb, it is next to useless for actually troubleshooting spark. You need an adjustable gap inline tester, to verify that the spark is actually hot enough to fire under compression, in which the resistance is much higher than at atmospheric pressure.
