Holley 4bbl leak
Ive got a Holley 4bbl 600cfm carb on my 302. It has fuel leaking from the bottom of the shaft coming out of the bottom of the housing for the diaphragm for the vacuum secondaries. Is there a seal that can be easily replaced to fix this? The carb was rebuilt about 2 years ago but the slight leak developed in the past few months.
Thanks

There are bushings, but I don't think that's the real issue, there should be no fuel pooling up on the throttle blades to even leak out. I would check the rear float level. It sounds a little high and allowing fuel to boil over into the veturies when hot.
