The primer on a 6.5 hp Quantum or Intek Briggs and statton engine is an air chamber that when you press it pushes air through the carby bowl and forces a small amount of fuel(gas) up through the main jet and into the intake system.
not getting gas.... needs carb cleaned
depends on the engine Briggs or tech, does it have a primer bulb. but safe bet right next to the carb.
yes... near primer bulb
Most common cause of surging is a dirty/clogged air filter.
If you get the model and serial numbers off the engine, you can probably find the part at a local mower repair shop or at Sear's.
Check the gasket between the air filter backing plate and the carburetor. Usually if that is sucking air then the primer won't work. Your best bet would be to just replace the gasket and possibly the primer bulb as well
You either have a bad bulb or a bad fuel line between the bulb base and the gas tank. If there is the slightest hole or crack in the bulb it will not work. They are easy to replace.
no gas, bad or disconnected gas line or cracked bulb. Possibly something small blocking the hole inside behind the primer bulb.

The primer bulb probably needs to be replaced unless either one of the fuel hoses leading in and out of the primer bulb bracket is clogged. Be sure you mark how each fuel line goes before you remove the bulb so you can replace them correctly. Hmmm. Thinking more about it: If the primer worked properly before disassembly, chances are you crossed up the fuel lines when re-installing. Try switching them.

Not easy w/out the proper tools. If you're sure you're going to replace it, you can tear it out w/ pliers, just be sure to get out the stepped plastic retaining ring that holds the bulb in. CAREFULLY use two small flathead screwdrivers to snap the new one in.
