<VV> Re: Idle mixture needles

[GYoungwolf@aol.com]

 If the idle mixture screws are blunt they are essentially ruined. You can 
refresh the tip by putting them in a drill and using sandpaper to sharpen them, 
but better to replace if interested in a smooth idle. The broken tips can 
usually be removed from the base of the carb using a small punch that just fits in 
the square cutout for the hole. (You should be able to see light though the 
needle holes.) Be sure the broken piece comes out or it will clog the idle 
circuit. Let me know if you need some replacements. (You should stick with good 
used steel ones as all the replacement brass alloy ones I have seen are too 
soft.)

Subject: <VV> Idle mixture screw question...

I've got a couple of carbs that I think are pooched. The idle mixture screw 
on both of these carbs is blunt at the tip. The carb housing appears to have 
the tip stuck in one of them. My question is, was a change made in these screws 
or have these been screwed down so tight that it's been smashed and ruined?
