Hi Guys,
Below are the photos & videos of RB30 Nikki carby throttle valve operation, taken from the bottom
of the carby while it's outside.
Does the primary throttle valve look ok?
It looks like it doesn't shut completely & sort of leaves a gap in the bore where the air can sort of leak through.
The valve moves freely and doesn't sort of "stick", but I wonder what we see in below pictures and videos can be thought as a slightly sticking valve?!
Larger valve with vacuum diaphragm attached to it is the secondary.
Smaller one is the primary.

I'm sort of happy with the secondary valve operation(mechanical movement and closing), but I can't say the same thing about the primary one though.
I would appreciate few opinions/advice from guys who know about this better.
Thanx in advance guys.
P.S. I posted the pictures on below posts. My issue is the above carby's running too rich on idling(cold or warm).
