Yes, you can cetainly try that. If you con't like what happens, just put them back. Two things to consider. First, you can buy materials to make a very accurate manometer for about $10 at the local hardware store. There are directions online. Second, I don't thinkyyou have enought "throw" with the screws to bring the idle down to an acceptable range. I think something else is going on. The throttle is hanging up, or the lower cables are too tight.
