Dellorto Drip?!?, Fix or replace Options

[UkonCornelious]

Good afternoon team,
I rebuilt my Dellorto DRLA 40s this summer and was excited to replace my oversized EMPI 44s with something that should run much better on my cammed 2056. Everything I read says 44s are too big for that size and my old set of Dells were the ideal change. They even have the CB Performance upgrade!

Based on my research, the problem I am having points to an issue with the internal plug on one side of one carb. I installed a fuel pressure gauge to verify it wasn't too much pressure from the electric fuel pump and it reads less than 2 PSI at the moment. One carb has fuel leaking into the carb throat down low, near the idle port holes. It is not overflowing from the center above the bowl. The other side of the same carb is also not leaking at all, giving more support to the theory that it's not a float valve leaking or being pushed open by the pump.

So... should I risk the repair involving the little lead plug(s), shop for a replacement, or look for a shop that may do the repair? I'm pretty savvy with most work as I did my entire 2.0L rebuild myself, but the idea of drilling into my vintage carbs is a little scary. If there's a more definitive way to narrow down the issue, I'd be thrilled to know.

Suggestions? I live in the Richmond, VA area.

Well that is the classic symptom. I used lead plugs. It was preventative when I rebuilt my 45's.
Today I would drill and tap it.
