I set all of my machines by ear, so I don't have a specific spec for tuning the carb. BEFORE you try to adjust the carburetor Make sure to repair the intake manifold. if you have a leak it will throw all of your fuel/air mixture adjustments off. Once you have the manifold fixed and you have rebuilt the carb try to start it before you perform any adjustments. It may just start without any adjustments being necessary especially if you put the adjustments back where they were before you tore into it. A good rule of thumb is to count the amount of turns that it takes to remove the air and fuel screws. That way you can set it back where it was.
From the sounds of it you are more likely to need to adjust the float height over the mixture screws and main jet. you do this by attaching a clear fuel line to the drain nipple on your carburetor float bowl. once you have done this you turn the fuel on while holding the fuel line up next to the bowl. the fuel level should be about half way up the bowl. you can find the exact specification in the service manual. if the fuel level is too high you need to bend the tab on your float up. If it is too low you need to bend it down. don't forget to check the float to see if it is full of fuel. this would cause the fuel level to be way too high. If your float level is fine and it turns out to be that the adjustments are way out to begin with, adjust your idle fuel screw all the way in and back it out 3 turns. this will give you a spot to start from. adjust your idle screw until you hear a change in RPM then back it up 1/4 turn. then set your idle with the adjustment on the throttle. For your main jet I have found that it is best to start out on the second notch from bottom up. But I would suggest that you leave the clip in the spot that it is in now, and adjust it after you get it running.
