Keihin Carbs... accelerator pump and oil injection nozzle Qs
So I tore into the Keihin carbs on my 1200 off the Rio. As I'm inspecting these... I got a few questions.
The accelerator pump tee's into the 3 nozzles at the tops of each carb near choke butterfly. I can NOT blow through any of these nozzles (by mouth). Should I be able to? I'm thinking they are either clogged... or have some sort of check valve that I can't overcome by blowing through them.
The oil injection lines connect to barbs that come off the sides of the carb. Do these have check valves built into them? I can blow threw them barely (by mouth)... but I can also suck back through them too. And they don't seem even... 2 of them feel about the same... the 3rd seems harder to blow through. I've sprayed them with carb cleaner.
Appreciate if anyone can shed some light on these nozzles for me.

Both have check valves, you are correct in your assumptions.
