Is the pilot jet on this cab part #92064 in the diagram supposed to be clear all the way through? I cannot get a piece of wire all the way through it but looking at it, I am not sure if is supposed to go all the way through. If it is supposed to be open all the way through, it seems it would be pulling unfiltered air into the carb. The engine runs good with the choke on, if I turn the choke off, I need to back out this pilot jet 1/4 turn for it to run with the choke off as if it is not getting the air it needs. I am sure this jet is not made to not be seated all the way. I am not to familiar with this type of pilot jet being on the outside of the carb as I mainly work on motorcycles.
