RE: 46 FX tuning problems
I don't know if you can't post twice or not so no problem , But I answered the question in there and Hobbsy deleted it which is RCU policy for manufacturer post.
But to give you some tips, the instructions say "Open the needle-valve to the advised starting setting and start the engine. If it stops when the glow plug is removed open the needle valveto the point where the engine does not stop.
When breaking in my engine I opened it 3 turns and continued following the instructons.
Good Luck.
