Using a Thermoquad with boost

Try the bigger carb first.

Do not TQ’s have nitrophyl floats?

Click the link above. The links thread has the builder grafting TQ floats to the AFB.

From the factory, yes they used the nitrophyl floats. However, they sometimes get fuel saturated and can sink. New nitrophyl replacements are available but so are brass floats which some people use to prevent the saturation problem. So a lot of those carbs may now have brass floats which work perfectly fine for non supercharged use.
