Tried running fuel lines direct to carb. Tried plugging (secondary?) fuel line coming out of tank and where it hooks to carb. Seems to have the same problem either way.
Stop wasting all of your time attempting to reengineer the device and just order a new primer bulb assembly...

This is the same problem I have with a Mac 3200. I have: (1) A line from the primer bulb to the front port on the carburator. (2) line from fuel tank, with attached fuel filter, to the other primer bulb port. (3) Line from port on back of carb. to ????. I thought it must be a pulse line, but not certain, and don't know where to run it to. Please let me know when you find out.

From the fuel tank to the carb, from the carb to the primer, from the primer back to the fuel tank. The bulb sucks fuel through the carb excess fuel is returned to the tank. HTH

SOURCE: Just replaced fuel lines and
Line from fuel filter goes directly into the inlet of the carburetor and the line from the snap in bulb that is marked "in" attaches to the other outlet connector on the carb. Last is the long side of the bulb goes to the return on the gas tank. The snap in bulb sucks the gas but not directly from the filter hose, it does this through the carb as if it were trying to not only **** in the fuel but also removing the air trapped in the carb. You'll notice that the bulb has a **** side and a discharge side, and the **** side goes directly to the carb outlet connector. I tried to make this a clear as possible, and I hope it helps.

OK, there are two conections on the back of the primer, the longer conection is the pressure side, so this has a hose back to the fuel tank, it will just push into the tank with nothing on the end, the shorter connection on the primer is the suction side, this pipe will go to the carb, the conection nearest to the metering cover of the carb, usually a chrome cover held with four screws, the other connection on the carb, nearest to the pump cover, usually alluminium held with a single screw, goes to the fuel tank with the fuel filter on the end, just remember the primer pulls fuel from the carb, into the bulb and back into the tank.
