Carburetor leak
Not a week into inheriting my Dads 67 I need some help.
The Holley carb is spewing gas out of oue front bowl at the "weep" valve on top as she warms up. I just finished a sniper 2 install on my 68 L78 Camaro, and am thinking of investing for the same setup on Dad's.
Any ideas? Easy fix maybe?

If it continues, the front bowl removes easily with just the 4 corner screws. Clean it out with carb spray, work the float up and down as you do this. Check the float height setting and reassemble with Holley's reusable gasket.

Give the top of the float adjustment screws a few wraps with a screwdriver handle. When a Holley is shut down hot and not driven again for some time the floats can stick to the varnish left behind from evaporating hot gasoline. When you start a car cold with this condition it will run lumpy and pig rich. Shut it down. Give the carb some sharp raps as above and that should cure it. I go through this same BS with my L78/Holley every spring.

It could be a leaking needle and seat assembly. Not uncommon in last several years.
