Engine won't stop..... on it's own.
I have a Tower46 that does the same thing.
I can look at the throttle barrel and see that it is fully closed but it just will not stop on it's own. It will have a very slow idle. So to stop the darn thing I just grab onto the spinner.
Other than this inconvienence...... the motor is great. Will turn an 11x6 APC prop at alittle over 12,500.
I will buy another.... when I need it.
