Small Engine Troubleshooting Problems? Ask a Mechanic Now.
Welcome to JUST ANSWER small engines, let me try to help you !! With the BX, two things to check, one, is the fuel supply to the electric fuel pump.Make a test hose and attach it to the fuel pump inlet, bypassing the first fuel filter and the tank and outlet lines, and drop the hose into the fuel filler opening. Run test and see if tractor still looses power. If it does, put hoses back, and remove the fuel shutoff solenoid, and tape up the hole and run with it removed. It may be loosing grip and is shutting off the power by restricting the governor operation .
