Fuel Leak all over intake manifold

Well, the 1920 that was on my '73 Valiant was the original with 49K on it. It was covered in grunge and appeared to have never been apart. It ran ok most of the time but sometimes would barely run after a restart, or it would experience a huge stumble occasionally even when hot.

Finally I started smelling a whiff of gas and it was the accelerator pump "hole". That great idea about ruptured pump diaphragms dumping fuel on a hot engine isn't just a 1920 thing either, most Holley carbs are like that. That and the float bowl gaskets are why I won't use a Holley of those types.

I found a Holley 1945 off an '84 Van. I modified it to use an actually base idle screw instead of the Idle Stop Solenoid, rebuilt it and it works fine. There are no gaskets below fuel level, it uses a common cup-style accelerator pump, and also a center-hung brass float.

The BBS should be great but try to find an unrebuilt original instead of a parts-store carb.
