Kymco bet and win 250 New carb?

[Magoogers]

Hello,
Im having carburetor issues with my bet and win 250. Trying to get the scooter running this spring, ive taken the carb apart. When I went to reassemble, I noticed the carburetor bystarter E-choke was missing the cylinder and needle as shown in the photo attached.
In the past ive had the bike running but never been able to get it tuned quite right despite my many tries. The carb has stock jets. If I accelerated too quickly the bike would bog. When tuning the fuel screw at idle, I couldn't hear any change in RPM.
What are my options, buy a new carburator with a new bystarter or replace the bystarter and maybe get a rebuild kit? Ive been able to find rebuild kits that seem to match the carburetor gasket from my cvk30 carb but im not sure which bystarter would work with my carburetor or where I could purchase an entire carburator.

Thanks

Would this carburetor work?

So I found the other side of the bystarter inside the carb. Ive ordered some alligator clips to test the bystarter and this generic bystarter from amazon https://a.co/d/4RwPTCS. If I can confirm the bystarter works I will ensure I try to tune the carb once its fully warmed up incase I was tuning when the carb was choked.

usually a good cleaning is all most carbs need. Now you definitely need a new bystarter...if you really don't have a needle it means your scoot was always running 'enriched'..as the needle starts out retracted and expands to close a passage as it heats up, cutting off the additional fuel needed when cold.

You can buy generic carb by starters all day long...and I'm sure Kymco sells them. Complete disassembly and cleaning all passages with carb cleaner and compressed air and making sure jets (especially pilot) are clean, as well as cleaning the passage your air/fuel mixture screw goes in. You want to see carb cleaner come out of every little hole in the carb, ensuring it is clean.

I don't recall many needing to upjet their stock Kymco carbs...I'd start with a good cleaning and then if needed you can increase your jet sizes? Do you have an accelerator pump on your carb?

It won't run with a defective bystarter.  Just buy another one - they're not expensive. Less than 10 bucks with free shipping. Don't be cheap! Chances are it'll run OK without any other work.  That's the genius of these carbs!  (Of course, a careful cleaning as suggested by others is a good idea, too).
