3310-2 seconderys flooding

Well i puled it a part the float is ok its not sinking,the needle and seat, there is something wrong there move the float up and I cant blow any air through witch it should be that way when float down sometimes i cant blow any air no air going in if i tap the top there she blowsssssssssss i have try ed the old needle and seat same thing,but if the float goes down to let fuel in and nothing, why is it flooding anyway,me stump.If it was to high pressure from my stock pump why it it not doing in the primaries thats fine.Thanks for the help.

If I understood what you meant there, the needle will have a small resistance to coming off the seat. (not much)
Could it be that the needle is hanging up in it's jet bore?
