The thickness of the gasket is important with a ripped gasket clean both surfaces and the gasket and let dry. A very light touch of heat resistant rtv on both sides of the rip and reassemble should take care of any leak.
I initially set the needles on those carbs using a 1/16 drill bit. Back the low speed needle out. Put a short piece of fuel tubing on the fuel inlet so you can blow through it into the carb. Insert the 1/16th drill down the throat of the carb and close the barrel until it just holds the drill bit. Do not force. Blow through the fuel line and slowly close the high speed needle until the air stops flowing. Now back the needle out slowly until you can just detect air beginning to flow. Your high speed needle is initialy set a small adjustment is all that should be needed. Now set the low speed needle as per the manufacturer's instructions and your initial carb setup should be complete.
