Not for a CV 40
Don't buy, they don't fit a CV 40 carburetor. Its a very loose fit, it wobbles when inserted.

Air/fuel mixture screw
Fit good but time will tell if it worth a crap or not

Fit perfect, works & adjusts great!
Quality, ease of installation and performance is worth every bit of this $8 upgrade. So nice to be able to fine tune the idle mix without having to remove the carburetor, especially after rebuilding or replacing my Harley Fat Boy carburetor.

Worked but didn’t have big change is turns out
Easily swap with idle mixture screw for 1999 HD Sportster. I feel like the needle doesn’t stick out fully and no matter if I bottomed it down it still was running with no changes. It still worked at 0 turns out and no change with 2-3 turns out. That’s the reason for the lower star rating

Better than a screwdriver.
Edit: sept 9th 2020.... still going strong. Was worth the money...Installed on a 1998 sportster 1200 Custom with the stock CV Heihin carb. Before installing I recommend cleaning the part with brake cleaner before installing as mine had a little chuck of brass and some small brass shavings in the threads from when it was manufactured, just to prevent anything thing foreign from entering and clogging your jets... no big deal you should always thoroughly check and/or clean any part prior to installing. Furthermore they do seem identical and the new one threaded in no problem. I did NOT have any issues with the spring provide as some other reviews said it didn’t fit. The only small thing I saw that could be an issue is the diameter of the very very tip is slightly bigger (like 1000ths?) which may or may not have sealing/seating issues but I’ll update once installed and tinkered with. So far I’d say it’s worth the money, will update if views change. Ride safe🤙
