Hey guys,
Having trouble that the secondaries don't appear to be opening / working right on this carb. Everything seems to move freely and stepping on the gas with the engine off the secondary opens and the air driven butterfly above that seems to move freely by hand. When driving the car you never hear that sound of the secondaries opening and the car seems low on power.
The engine is a 351C 4V with a Torker II manifold. Since everything is moving freely my thoughts were that free flowing manifold was making for lower air movement and the air driven butterfly just isn't getting enough air past it to open all the way. That's totally a guess though. This was on the car when I got it and don't know if it ever worked right.
Appreciate any advice in debugging this.
Thanks
