HI Wolfgang
Let me first start with recommending buying my book, link below, it
s exactly what you need right now . It does deal primarily with Holleys, but the general idea is the same, and you can easily follow the process.
That said, can I help? My first input would be that a throttle response issue on an otherwise pretty OK functioning carb is usually not a rod/jet issue, more likely an accelerator pump issue. You need to get that fixed first before you start playing with rod/jets, or you risk going way too rich on rod/jets in an attempt to compensate for a incorrectly set acc pump.
Let me know if you have any questions.
