If you need to slightly enlarge a fuel jet orifice , If you are lucky enough to have a guitar handy... cut an inch off of the slack on the b string on a guitar and use it as a file to open up the itty bitty hole in the jet. Luckily I have some Nickle wound on my guitar!

it works great, I took a stock jet out of an old carb, presuming they almost all come with a 70, I reemed it out to about the same graduation as the set of jets I got off ebay 45-70. To about a 72 or 73? Its what the ld100 was needing.

A strand off a brake cable will also clean the jet

But when it comes to changing the hole size in a jet, It's best to use a micro jet drill bit set
The jet hole can also be soldered closed and drilled any jet size ya want with a micro jet drill bit set
Micro drill bits, no guessing involved ya know what size jet ya got
