I'm currently rebuilding my carburetor on my Yamaha moto 4 350 1987, first time I rebuild a carb 😅 ! It was leaking fuel from the overflow and inside the intake ....
When I took off needle (the platic top part was stuck like crazy) I had a spring and inside the kit there is a spring, an O-Ring and a washer.
Left is the needle that was in the carburetor and right is the new set (I already tried to mount it but it didn't felt right and I accidentally broke the o-ring)
Anyway, I saw in some videos and diagram that there is no spring in here. So should I put the spring back ? And where ? On top of the needle or bottom ?
This is an original Mikuni carb :
Thank you ! Also if you have any additionnal tips please feel free to share I want to learn the proper way !
