P3314 is impossible to start because I cannot pull the rope with enough force to really spin the engine. The rope feels like it is caught on something, but it is not. With spark plug removed the .engine is easy to spin which led me to think that a timing problem was causing the hang up. I ruled that out when I found that the hang up happens even with the kill switch engaged. I have also ruled out carbon build up. Anybody have any theories? I appreciate any advise or ideas offered. Thanks, Ted
