I was recently given a TCM FG25N2 model lift. The Lift is fairly clean, no leaks, and was in working condition. The original owner said the lift started running rough like the carb was in need of a rebuild. Well he had someone rebuild the carb, and it still is not right. The lift has not been worked on in a few months, but I loaded it up and brought it to my shop. I put clean gas in it, and a fresh battery in it, and it didn;t want to crank. It did sputter a couple times. I gave it a shot of starting fluid, and it would kick over, but wanted to backfire thru the carb. I'm new to forklifts, and not sure at this point what to look for. I would assume the backfiring means a timing issue. I am going to check the timing, replace plugs, wires, etc... and try it again. Any advice is greatly appreciated. Thanks ~Jackson
