i have a 1996 yale glc050rfnuae082 serial# E187VO4152U. its does not want to start. I thought it was the diaphragm since it had a little tear. i replaced it with a new one but still wont start. it smells very rich after its been cranked a couple times. i never have worked on a forklift before but im pretty handy. im getting fuel to the carb but after that i dont know what to do. there are no forklift mech in my town.
