ok, maybe this could sound like a dumb question but anyway here it goes, when should the secondary throttle should open completely? mine just opens a little bit at full throttle, is this normal?
the air valve including the choke valve, they just open a little bit, and the engine is running
The choke should be all the way open if the engine is warmed up. Unless you have a whole bunch of engine, you'll never be able to get the secondary air valve all the way open. The engine simply can't use that much air.

Even under load, a stock engine won't open it all the way. This carb will support considerably more HP than these engines put out.
