I don't have a primer bulb on the motor itself. I have no knowledge of this particular motor except that it started for the old owner and hasn't started for me. I know these guys are tricky with their starting procedure though. I messed around with the choke and throttle, and that's about it.
I used to have an old motorcycle and worked on it myself, but I lost interest and don't feel like I've retained much of that information. My neighbor is knowledgeable on car engines so I could borrow a tester and tools and maybe get some minor help from him.
Okay, I'm pretty sure it'll run okay you just don't know how to start it. So next to the start button is a knob and you think it's a choke but it is not. It's a fuel primer.
So follow these steps, and let's see if it'll run. First of all I'm assuming you've got it hooked up to water or you've got it in a barrel, correct?
On the fuel line, is a ball and that is also called the primer ball. Squeeze it a bunch of times until it gets stiff. On the tiller arm twist the grip until it says start, that's assuming it hasn't wore off. Now pull out the knob that you think is a choke twice. After you pull it it should snap back in or at least halfway. Now push the start button. When you pull the knob you should feel resistance like a plunger. What it's doing is spraying gasoline into the intake and carburetor making it easier to start.
If that doesn't work I would grab your neighbor and show him the instructions and see if he can get it to go. Report back
