OK stupid question but where is the sight plug on this one? I see pressed in plugs is all it looks like to me... Also looks like there is only one metering block on this carb, and two idle adjustment screws, one on each side correct? Idle screw is to the right of the red spring wrapped adjustment screw at the front of the carb if I am getting this right. Close-up picture attached.

I read 14 inches of vacuum at idle when warm. Adjusting for my 4000ft elevation, that's 18 inches equivalent at sea level. The car definitely smells "gassy" all the time.

Thanks for the info - explained nicely.
