Back story, this unit had a bad converter seal and leaking front pump seal. Removed engine, replaced seals, and re-install engine. Now, I cannot get the unit to idle, as well as hard starting. Will run great when pedal is fully depressed, or anywhere between 1/4 throttle to full throttle, however when pedal is released, unit stalls out. Replaced accelerator pedal (electronic) combed over every inch of engine to make sure I didn't miss anything. Any ideas?? After unhooking battery, and waiting 5 minutes or so, can hook up battery and unit will idle, then stall out when pedal is depressed at any position. Is there a learning procedure?
