LT-1 Replacement Carb Suggestion

[VintageMusclecar]

Gary;

For no more than what they cost, go get a new pair of HOLLEY .110" needle & seats (stay away from the generic rebuilder jobs, esp. the Borg-Warner styles!) and a pair of new brass floats. When you re-assemble the float bowls, baseline the floats by inverting the bowl and running the floats down until the top of the float is at the bottom of the float hinge screws. That usually gets them very close.

Make sure the floats operate freely and don't stick or have any tight spots. Sometimes you might have to gently "tweak" the float hanger "ears" to get everything to set just right.

Also, while you've got it apart, check the metering block surfaces on the main body of the carb and see if they've ever been machined flat.

Keep me posted.
