How much for 71 Thermoquad?

Hysteric.

Replying to post #131. 'Inefficient operation'.

Since they were likely not concerned with emissions in 1932, inefficient operation could refer to fuel economy &/or power. But it doesn't matter anyway because though similar to the 72 TQ, it is not the same. The TQ has the nozzle pressed into a sheath with clearance around it. An air bleed connects to this gap. The patent carb has none of this.
