That is good news, Jen, but I'm not surprised. Now since you've already serviced it, the next step is to see if it will start. Remember the limitations of that coupled choke system: we don't want either to flood it, or to under-choke it. You've just been pulling it over with the spark plug removed, so hopefully any excess fuel in the cylinder has been blown out by now. I suggest you install the spark plug (doing it up moderately tight, so it won't leak air) and connect the lead. Set the speed control at maximum so that the choke is pulled out fully (full choke) and, of course, the kill switch is not operating (it operates at the other end of the speed control's movement). It is safest to flip the clutch lever over so its handle is toward the engine, so that the reel will not rotate when/if the engine starts.
Remember, the most you can hope for is that the engine will fire a couple of times then die in agony. It cannot run with full choke. If it fires, and you have superhuman speed and strength, instantly move the speed control to mid-range before the engine dies. More likely it will die by the time you get there. Don't worry if that happens, just put the speed control lever in that mid-range position and pull the starter immediately. It should start, and run properly. To stop it, move the speed control fully to the opposite end of its range from the choke position: that should operate the kill switch, and stop it. If it starts but won't stop, you'll have to pull the black plastic cap on the spark plug lead upward off the spark plug.
Please let us know what happens, of course.
