I just bought a White Brothers fuel mixture screw for my CRF250 and am not sure how to install it.
The new screw has an o-ring between the threads and the adjusting knob. The original screw has the o-ring at the very tip.
Do I need to use my original o-ring? I hope not because it is toast.
The new o-ring doesn't seem to fit into the hole in the carb. Does it just sit against the carb to create a seal or are you supposed to mash it into the hole?
Thanks
