I can put a 0.3 drill in the new idle jet easily, put in the huayi could only just manage to push the drill in, with 0.35 drill I cannot get in either idle jet. The ruixing had the same result as the huayi but the keikhin I could fit a 0.35 drill. The next drill size I have is 0.4 and doesn't fit in any.
