Posted picture on Branson 2910 warranty thread. I put a picture of the check valves on injector pump. I was trying to find out which one to take out and what to do with it after removal. Tractor starts very good, but it puts out a lot of white smoke for 15 or 20 seconds. Put a bottle of Lucas injector cleaner in tank; didn't particulary help smoke but sure seemed to run better. I will post picture on this thread and hope someone can tell me if check valve is still in line and what to do with it. I bought this tractor used with about 500 hours on it. Runs great after white smoke quits.....BL
