How do i adjust the screw on the carburator on a Jonway yy250t?
the screw is placed horisontal under the carburator, so it is very hard to adjust while idling, any tips? I have a CO-tester, but i dont know what the CO should be. I guess 3-5% but i am not sure. Are there any other way to adjust?

Hello everybody.
I have been reading your problem, to find out whats wrong with mine. It was stalking and when i held my hand on air intake it was running much better. The solution was too small main jet.
So if anybody will have this problem, check your main jet.

Thanks for all the information i get here, i will try to help you guys as i can

Regards Peter
