What if when you pull it there is no resistance sometimes and other times there is? Is that normal?
I think your one-way bearing is shot.
Also, Fast runner Please search before starting a fourm, their are many guides on how to start a nitro engine.
That is exactly what i was thinking, Spray some carb cleaner on that bearing, that usualy works for a while, then buy a new one.
Have fun!
