<p class=MsoNormal><font size=3 face="Times New Roman"><span style='font-size:
12.0pt'>Sounds like an air leak somewhere. Perhaps it gets overcome at full
throttle or is worsened at those specific RPMs because of harmonics in the
vibration of the carb. Might be a crack or flaw in the carb, but more likely
it’s in the mounting, either O rings or some other flaw. They can be hard
to detect and locate. You could use the carb cleaner method—spray a
little at each joint or suspect area and listen for changes in engine sound.
I’ve used the ultrasonic detector I use for finding leaks in surfboards to
some effect, a leak sounds like a calliope, but there’s a lot of other
noise to sort it from. <o:p></o:p></span></font></p>
