I also am just trying to start my OS 61FX for the first time. It started once and ran for about 20 seconds but when I tried to start it again it has flooded every time. I have followed the procedure for clearing the engine out by removing the glow plug and closing the needle valve then using the starter to turn it over. But I have been unable to refire the engine since and am very frustrated does anybody have any suggestions I can't find any advice in the manual.
Thanks Ron
