Re: Carb cleaning; must I remove the orifice plugs?

[frankr]

Under the circumstances (silicone chunks), I think I would remove them if they will come out without a lot of grief. You are supposed to use a special screwdriver with parallel sides. A regular screwdriver tends to spread the soft brass slot, making them tighter than ever.

But if you feel you can get all the junk out without removing them, that is fine also.

Yes, those are metering jets and as such are highly precision holes through them.
