I posted a message awhile back concerning what the maximum RPM's on a B are. I had an analog tachometer and could only get 900 RPMs. I checked everything on the tach/wiring and it appears to be fine. I was able to get 1400 RPMs by pushing the throttle link that is near the carburetor. However, I cannot get the motor to that level using the normal throttle on the stearing column. Should I be able to get more from the throttle lever on the column, or do I risk overreving the motor. Thanks again for the help.
