We're not familiar with any particular problems with respect to the rear needle on the O.S. Max .46 FX engine. However, that being said, the #40K carburetor will not fit the .46FX because its throat's outside diameter is too small. The #40B carb has a larger O.D., so the #40K carb will not seat properly and seal onto the .46FX engine.
