The TQs' Secondary Activation latch needed to be wired down or it would "jump and miss" leaving the owner with a small 2 BBL. at W.O.T. The black plastic floats were also a disaster and were known to turn into sponges overnight which was odd to say the least.I did try a 650 Holley with mechanically secondaries .. I didn’t feel they were as good as the vacuum secondaries carbs so off it went .
The TQ was brought to life by adjusting the secondaries to kick in at better timing .. simple adjustment.. I did like the TQ’s . The benefit was with the small primaries and huge secondaries and was a great mix between economy and power for a treat car.
To that’s what the Six packs did also but with 2 larger 500 outboards and the small 350 primary carb . Floor them and the roar was assume hahaha ..
The Secondary Air Door also required a rather precise adjustment to allow air to switch directions exactly in line with the secondary tubes.
The models with the one big Air Vents and goofy electrical connector didn't work nearly as well as the ones with dual Vents.
