Oh is this the part were I take out the carb and measure the float level from the bottom surface of the float to the machined gasket surface of the carburetor body and it should be 1.5 inches or 38.5 mm? And if its out of that I have to literally bend the float tab?

As for the choke, it opens slowly when I start the engine. When warmed up and filter on, I hear a click every now and then. Is the that right or do I need to adjust this also?

Thanks.
