Lmao yes slide throttle to top it of the medal ring that clamps around the needle slide is currently lost on my back porch now too
gonna sweep area up a pray I find it. But there is also a plastic ring that clips under that ring I still have wonder if I’d be ok. are you familiar enough with these Amazon “mikuni” knocks off carbs
Both the needle circlip, and the circlip retainer are critical to function because without the circlip the needle basically falls down the main and plugs it entirely which is bad, and without the retainer the throttle response goes to $hit because the intake velocity will jam the needle in place which delays the deceleration and can lead to an extremely dangerous situation.
(some use a spring clip that grabs the inner walls of the slide for a retainer, others use a "Pac-Man clip" wich is essentially a slotted washer, other still use an odd circlip that is both clip and retainer integrated as a single part)
I'm familiar with motorcycle type carbs, mostly Keihin. Functionally speaking there is no difference between a VM22 and a PWK24 they tune by the same exact methods as do the majority of slide carbs.
I prefer the PWK because it is physically impossible to put the slide in wrong because its a D-slide, where as with a round slide like the VM, as well as the, PE, PZ, and a most other carbs can be installed wrong by 180° rotation effectively jamming it wide open since the idle screw ramp ends up on the wrong side of the body.
The first thing you need to is find or replace the missing clip and retainer.
Then you have an actual chance of making it run properly
