I spent the better part of two years fooling with a Holley carb. Set the floats, idles well. Go for a ride and the fuel would be gushing into the motor. Back to the garage, reset the floats, idles well, go for a ride and the motor would be starving for fuel.

These "rides" were about two blocks long.

Switched to an Edelbrock #1404, set the idle screws and took a 400 mile trip. That was 11 years ago and I haven’t touched the carb since, though I should probably rebuild it.

No power valve to screw up. Springs and needles are changed without a teardown of the carb, just remove the top plate.

You couldn’t pay me to use a Holley.
