I've tried to find a knurled adjusting screw for my old Keihin carb without any luck (lot's of leads though that didn't work out). I'm going to try to build one (I've got a lathe), but what I need now is an OEM a/f needle. I don't want to take the one I have in the carb out until I can feel comfortable that this is an option. Even if I can't make one, the slot on mine is getting pretty rough (I'm sure I can clean it up if necessary). So anyone have one that I can buy? I'm looking for one for a later model carb that is inset inside the carb body that had a seal for EPA over it, but I'll take anything just in case....

Thanks,

Dave

 

Here's the needle after I modified it. I've been running it for a few months now:
