I took apart the cannon assembly to install the Cliffy. I got it back together and levelled it. However, the cannon now does not rotate enough to the right, and too much to the left. It is the motor itself that creates this unequal arc, nothing is physically impeding the assembly. I cannot see any way to adjust the motor itself. It seems the problem would be fixed if I could somehow rotate the motor rotor about 10 degrees or so. Anyone have this problem or know how to correct it? Cannot hit the right pop bumpers from the cannon the way it is. Thanks.
