Need help to set idle

[Charlie ny]

ds,
In my experience the best...most trouble free....nozzle bars are those
that sort of resemble an upside down 'V' with an integral vent tube pointing
straight down towards the venturris. From the photo of your idle tubes it APPEARS as
though you have the tall nozzle bars which kind of look like the letter 'N' with one
vertical leg missing. Let us know which nozzle bars you actually have. The 'N' type
are very fussy about which idle tube can be used and further more there are about
6 different 'N' bars and just as many variations of idle tubes to service the 'N' bars.
Let us know what bars you have and we'll go from there.
