I have a Big Boss 4x6 that has an intermitent starting problem. In neutral or forward gear it will only start if I push the throttle enough to close the switch inside the throttle assembly. If I leave the throttle go the engine shuts off. In reverse, the only way it starts is if I hold the throttle open slightly and push the reverse limiter button and then hit the start button. If I either release the button, or the throttle, the engine shuts off, if it is in reverse. Once in a while it will start without any problems and everthing works fine. The machine can be hot or cold for it to act up.

Any help with this would be greatlly appreciated!!
