Hi guys - I'm setting my float valve levels on my MC28 and I found the same problem as "NSR lover " - each time I adjusted the metal "tab" on the float I got the same measurement ( 19 - 20mm) no matter which way I bent the "tab".I checked the Tyga procedure and found it basically the same but the floats were in exactly the opposite position to the ones shown in the Honda service manual - the Honda pics show the floats at the top and Tyga show them at the bottom although both are at 90 degrees.I set mine up the Tyga way and was able to get the required 13mm from the carb base, hopefully I have set them correctly ??
