Very good advice. Be sure the throttle opens fully, but that there is no strain on the throttle lever when the pedal reaches the floor. So many of the Tri-Powers I restore have the throttle lever...

Please let us know how it works. You may know that '66 is the only year Tri-Power that has a center carb bracket that allows adjustment for throttle cable length by bending the center carb throttle...

Your center carb is the most difficult to locate, dur to it being used only on 1966 Tri-Powers. I believe Oldsmobile used the same casting number, but was machined for ported distributor vacuum.

You are wrong. The vented base gasket was used on all '65 and '66 Tri-Power carbs. The theory was that there may be fuel on top of the throttle plates, causing difficult hot starts.

That makes sense. The small holes don't interfere with idle, but flow enough air to keep the throttle plates clear of gas. There is sometimes a small amount of fuel that collects on the end carb...

Need large 2G carb or airhorn.

I need an airhorn lor complete carb like this. These were used on '68-'69 Pontiacs with a 2 barrel carb. Or, I could use the correct '66 Tri=Power center carb airhorn, which is casting number 7031587.
