The main jet is in a brass carrier. It’s likely the entire carrier
will unscrew when you unscrew the main jet. You can then
unscrew the main jet if you secure the main jet carrier with
an 8mm wrench.
There is a brass bushing that fits in the bottom of the
carburetor body. It interfaces with the main jet
carrier. Remove the bushing from the carburetor.
Note that this bushing has a beveled end and a square-cut
end. The beveled end will interface with the main jet carrier
when these parts are reassembled.
Remove the slow jet with a flat head screwdriver.
Pull the slow jet from the carburetor body.
