Amazing to me is that the hand primers fitted to the 150/172 series may only provide fuel to just one or two cylinders. In this case I always find that using the accelerator pump by pumping the throttle is preferable.
Bypasses the carburetor? I'm guessing you've never had the cowl off an aircraft let alone a carburetor apart? The accelerator pump is
part of the carburetor.
Yes, there are a few engines out there without a primer and using the accelerator pump is the recommended way to prime them. It's not an ideal situation though and they didn't add primers to all the later engines because they wanted them primed with the accelerator pump did they?
