Yup. Thanks Jon. The problem with the stamp on any Jet, no matter what, is that it's 60+ years old in our case and this means that long of opportunity for mechanics and novices alike to drill out the Jets due to the conditions at the time. Different gas, other issues with the engine, etc. You simply can't take the number at face value. Another reason to purchase the 115 pc drill bit set so you have all the numbered bits.
