YS 140FZ Help

[jim ivey]

Hotrod
I know you have the engine running now ,but I feel something is wrong with 
the low end adjustment.That is a air bleed and if you have to turn it that 
far out there may be something blocking the oriface.That many turns says to 
me the needle has no affect.
I would still take it apart and inspect very closely the low end needle 
assembly for foreign (something )matter that doesn't belong there.
Just more tho'ts
