Stumble with rebuilt Thermoquad /340

Lucahemi, the TQ has a lot of little things to contend with and look after. The slightest adjustments effect the carbs running and operation. RustyRatRod can take care of you on this. Just take your time, a step at a time.

The heat riser for the choke operation hampers the carbs cold running effort. A fully warmed up engine is a must without the choke operating. With the engine/carb running under temp, it will be cranky and a pain.
