Engine efficiency, ambient temperature, humidity, and altitude have big enough effects so as to make some other guy's setting useless to you.
You really need to get yourself a couple of main jets, and keep going down in size until you start getting the throttle response you are looking for. Once you achieve that, go to the next smaller main jet. See if response improves. If it's still slightly rich, THEN move your needle clip up a notch. If it gets better, but not perfect, move it up another notch. If not, move the clip back down to where it was, and go with the next smaller main jet, and repeat.
Here is a sentence out of the link from what is probably the best description and troubleshooting guide I have found: "If the engine is having troubles at low rpm (idle to 1/4 throttle), the pilot system or slide valve is the likely problem. If the engine has problems between 1/4 and 3/4 throttle, the jet needle and needle jet (most likely the jet needle) is likely the problem. If the engine is running poorly at 3/4 to full throttle, the main jet is the likely problem."
There is a reason that needle has five grooves on it. Don't be afraid to use them.
Here is the link. I highly recommend reading all of it before proceeding.
