For one thing, it's not the carb you're looking for info on, it's the entire motor. (granted it's all stock equipment on the motor) If you locate an owners manual for your year, make, and model outboard, it should have all the info you need. Next, you need to consider what part of the carb the fuel is comming from. Carberators are pretty basic, it doesn't matter if it's on a boat, ATV, or what ever. They all work the same way. Check your seals on the carb for one. If they are torn or worn, change them. Check all the screws and make shure they're tight. And so on and so Forth. Next, once you've done all the maintenence, re-install it back on the motor and tune it. Never tune a Carb starting from Lean. Always tune from a RICH setting. This will keep you from damageging your motor, especially if it's a 2 stroke. If you're able to find the repair manual for your particular motor, it SHOULD explain how to adjust the carb. Other wise, do this. Screw in both your air and gas screws in all the way. Once in all the way, unscrew each one 2 and 1/2 turns. That's a pretty general setting, it doesn't matter what you're going with. Now, just tune it from there. If it's a two stroke, you WANT blue smoke comming out of the motor, if you don't have blue smoke, you're running too rich and will destroy your motor. Make shure you put a couple extra ounces of oil in your gas mixture too if you have an older 2 stroke motor. Too little oil in the gas is devistating to a 2 stroke, a little too much will just make it smoke a little more and you won't get quite as much power out of the motor, however, it will make your motor last a whole lot longer considering how antique it is, it just give it more lubrication which is a good thing. Well, I hope I was of some help.
