"The two idle screws,how much do they need to be turned out?" ASSUMING the carburetor is in good shape, with no plugged passages, adjust them 'til it idles nicely... that's the beauty of old stuff over modern emission-conrolled engines... the old stuff can be adjusted 'til it runs well! (There is one idle screw for EACH cylinder... essentially two separate carburetors sharing one float bowl.) "Whats the big brass screw on the bottom of the bowl? Witch way does that screw have to be?" The big brass screw controls the gas flow in the "LOAD" circuit... the more you back it out (CCW) the more gas flows to the load circuits in BOTH barrels. "I DON'T want to pay $250 for rebuild,their doesn't seem to be much to the carb." There's MORE passages in there than you obviously THINK there are! The fact it doesn't run well proves some are plugged. You need detailed instructions, one of the videos on the market, or the help of a pro, if you ever intend to get it working properly. "I don't have any oil in the bottom of the oil bath air cleaner,would that have something to do with it?" Clean the oil out of the intake tube, clean and refill the air cleaner cup with engine oil, to the level indicated by the marks.
