Can anyone tell me the difference between the 55HZ and 55HZR other than the carb setup?

The "R" has a built in regulator that regulates the fuel delivery as you can see just hanging on the carb:

Heres the 55HZR:

Heres the non R just the 55HZ:

Heres the 91HZR:

actually a regulator not a pump if I am not mistaken. I know they sound the same but a pump and a regulator work completely different

Yes that sounds more correct, flyboy907. A regulator, since the tank is under constant crankcase pressure. The regulator, regulates the fuel flow inside the carb for a more constant fuel delivery or flow to the engine.
