hmm, I guess I'm a little confused here... you say the "pot" wasn't seated. What is the pot? :-) I took the base apart, and inside is a large "shaft" which is the throttle input I presume, the button wiring running inside the shaft, leaving through a hole and then to the circuit board. There is a brass half cylinder that is connected to the "throttle shaft", and I assume THAT is what is actually measuring the movement. However, It seems inaccesible, unless I missed some screws somewhere. If you can explain any further, please do. If possible (Who knows, the problem could very well be somethig else) I would prefer taking care of the problem where it exists. Thanks again for the help!
