If the jet plugs are the issue, Snap-On made a socket tool to use for their removal. I have 2 in my possession. Otherwise use a screwdriver with a very wide tip. Most screwdriver tips are too narrow, and won't give you enough leverage without screwing up the screwdriver slot. try a screwdriver that has a hex on the shaft to give you more leverage, use it with an open end wrench on the hex. Put the carburetor body back on the base, then mount the base in a big vise to hold it securely. this way all of your effort will be directed to the jet plugs, not to trying to hold the caruretor body.
