Weber woes, Please save me from insanity Options

[wbgoggans]

I’m at my wits’ end with my Webers.

They’re a pair of Spanish 44 IDFs. I’m running a fuel pressure regulator set at 2.5 psi, have set and verified float levels at least half a dozen times, and have rebuilt them again, and again, and then again for good measure.

Despite all of that, I’m still getting fuel in the crankcase.

For the life of me, I cannot figure out where the fuel is coming from. At this point, I’m so frustrated that I can’t tell up from down anymore, and I don’t feel like I’m following a logical diagnostic path.

Before I bite the bullet and spend $1,000 on a new set of Webers—or $400 on some Chinese knockoffs—would anyone be willing to take a look at these carbs? I’d be more than happy to pay shipping both ways and compensate you for your time if you can figure out what’s going on.

I’ve got a serious case of sunk-cost fallacy at this point, but more than anything I’d just love to understand what I’m missing so I can finally sleep at night.

For those about to suggest the basics: fuel pressure has been verified at 2.5 psi, float levels have been set and rechecked multiple times, the needle and seats have been inspected and replaced, and the problem persists. The fuel tank sits lower than the carburetors, so gravity feed should not be a factor.

Thanks in advance for any help or suggestions.
