What does jetting a carburetor mean?

Can you drill out carb jets?
By drilling out your stock main jet to larger sizes you will be able to narrow down what jet size your carburetor needs. You will need a numbered drill bit set. If it’s lean and you need to increase the size of your main jet, drill the jet out with the next size larger drill bit, which in this case is the #60 bit.
Do carb jets wear out?
It’s rare for jets and needles to need replacing. They’re brass, so they don’t really corrode. The needles can become tapered in the middle due to wear from rubbing the inside of the jet, but it takes a lot more than 8,000 miles to do that.
