The needle may also have been screwed in too hard or tight. This would cause the needle to have an indented ring on it where it would seal on the seat. If this is the case it would cause the needle to always pass fuel no matter how tight you screwed it into the seat area, ie. a rich running engine with the needle screwed in.

Dave, if you want to go that route, email or PM me. I will make one up and send it to you for free. Throw the old one in the trash..

Thanks for the idea and the offer Andrew! I have a well used .46FX here that I can take the metal needle valve assembly off and modify to suit the .46AX. Before than I do that, I will try to tune the engine using the technique recommended here. If that doesn't work and my needle valve off of the .46FX doesn't work, I may take you up on your offer Andrew!

Thanks again guys for all of your recommendations.

Re: Help with OS .46AX

Dave, I think step NO1 , get in contact with the previous owner and find out what he did to it. It almost sounds like the needle has been over tightened. ken

Re: Help with OS .46AX

First thing I would do is take the high needle out completely and make sure that you can blow fuel through it easily. By the sounds of it there is something stuck in the needle seat.
Good luck
