Sorry for the delay in posting. I finally got the unit in the shop and was able to test the rack. The rack works smoothly with the fuel shutoff lever but does not move with the throttle control lever. The throttle control lever has spring pressure from inside the rear housing and moves smoothly with full cycle. Again; moving the throttle control does not move the rack I've tried various positions of the rack by using the shutoff control and the engine starts each time, the runs for 2 seconds and quits. There is a good fuel supply going to the pump. Any advice would be very much appreciated. Thanks.
