I recently removed my fuel/air mixture screw on my Hitachi carb and found it to be severely worn. Is there any way to machine these screws or buy replacements? It seems like you could reshape the end and the screw would just be a little shorter, but still work?

Hi,

 

Where is it worn? Do you mean the tip of it? Yes you can work it over with your choice of fine abrasive wet/dry sandpaper. A good used one shouldn't be too hard to find on this board.

 

Or do you mean the threads are worn, sloppy? Blue loctite will take care of that.

Yeah, the tip is worn, but the threads seem OK. It still has a pitch at the tip, but there is an abrupt decrease in the circumference about a 1/4 inch up. It's probably not quite as bad as I'm making it out to be, so I think that I will try and smooth it out with some sandpaper and see if that helps, otherwise I'll be looking for a replacement.
