This statement shows your wisdom beyond your years... :-)
1. Do you have a syncrometer, flowmeter or vacuum gauge of any kind? If not, you will need to buy or borrow one. You can get close by ear, but that takes some experience...
2. Another good purchase for learning with would be one of those nifty sparkplugs with a site glass that tell you if the cylider is running lean or rich. Otherwise, you will have to just go by ear and checking your plugs one at a time unless you run an O2 sensor, but even then it just gives you an overall picture and not individual cylinders...
First thing you should do is to make sure everything else is in tune and to spec. Adjust your valves, make sure you have good spark plugs, wires, cap, rotor, etc... If you haven't got an electronic ignition yet you should consider it. Once these basics are taken care of, then start in on the carbs. For one, if your engine is pretty stock other than the carb, you are going to have fits getting them to run as well as some other options, but it can be done. Get the flow meter on them and make sure they are syncronized at idle and around 3000 rpm's. Then what I do is take all my idle mix screws to zero and then back them off one and a half full turns just to start. Then, adjust them out one at a time until you hear the motor start to stumble. Then go in with it until the motor starts to stumble again. Take note of the difference in the amount you turned it out and then back in and set it half way between the two. do this to all four cylinders and you will get really close.
Good luck!
