Title: Lower idle air bleed/feed?
Post by: ejowrench on April 05, 2014, 03:25:07 PM
Just read about the lower idle air bleed hole [in the main body]  on some Rochester carbs also work as a 'feed' during off idle. As the throttle blade starts to go pass this hole it is subject to manifold vacuum, thus pulling a little fuel out of the idle tube for a smoother transition.

My question is, does the Q-jet use this feature and how will modifying this hole affect the tuning?
