Re: what kinda carb is this
Many people hate the Q-Jet
Many people hate the Carter, Holley, Weber (take your pick)
They are all good, in the right hands.
The Q-Jet is on of the finest carbs built, once dialed in. The small primaries with their high air velocity gave greater milage, better idle control, more sensitive part throttle, and the massive secondaries really brings in the power on demand. When it works.
As with all carbs, clean fuel, proper maint, and it just works.
I vote for a proper cleaning and set up and use it, if the throttle shafts are getting sloppy I know a machine shop that will rebush and seal the shafts BETTER than new.
