Can you provide me some basic instructions on tuning my smaller (less than 120 sized) SuperTigre carburetor?
To properly set up your carburetor, there are a few steps… Make sure the spraybar is set so that the fuel slot is pointed straight down the center of the carburetor. You will have to look through the carb from the bottom, with the venturi opened to full. Loosen the two screws next to the high-speed needle valve to rotate the spraybar so that the slot is centered. The idle needle can be seen in the slot of the spraybar. It looks like a piece of wire that has the end squarely cutoff. It should be less than one-half way across the slot when the venturi is opened to full. The high-speed needle should be opened about 2-1/2 to 3 turns out from closed. All of these settings are very rich. You’ll have to start the engine at about 1/4 to 1/3 throttle. Once the engine starts, advance the throttle to full. You can then lean the high-speed needle until the engine is running just rich of peak RPM. Once you have the high-speed needle set, you can retard the throttle a bit and use the idle needle t
