Does it matter if this o-ring is on the idle jet. It's small and thin. And apparently not available.
Number 23 in the diagram.
Put a different carb on maybe,
I would not leave that O ring off .
I'd try measuring it and have a look around for replacements .
They may not be available from Bing or the OEM , but I'm sure they exist elsewhere .
It's very likely they are available from : https://www.mcmaster.com/o-rings
I might have a spare jet that has the o-ring present, I'll try and dig it out.
We had the same problem with big Honda idle jet screw o rings . Very small , but also very important . We found suitable replacements and never again worried about it . ;)
You can't be the only one with the problem .
I would get a 17 Bing for it instead. Gotta chop all the air filter mounting stuff off of it, but your moped will thank you profusely. Our old korado went very close to 50 on stock gearing with a 4p and a 17 Bing.
Korado cylinder LOVES a 17mm widemouth bing. Personal experience speaking, I blasted all over the place on mine and it loved high revs.
With a 17mm bing and a pipe, filter, and stock 14mm korado intake what size main jet and needle clip position would you all recommend?

Stock intake you got to drill/dremel out stock intake to make it bigger like 15.5-16mm ID first for good gains
If you swap it out to a round Bing atomizer in the square I think 70s was where we were at. Idk what square sizing is like.
Dremel out the intake or intake port?
I'd probably opt for a 17mm regular bing as opposed to keeping the square one
17 round Bing uses square bing jets unless you swap the atomizer.
