Fuel leak from Weber 40IDA

[Black 993]

Gang -- is this just a gasket that's leaking, or is there something more significant going on? I noticed recently a gas smell after a drive, and the leak is coming from the red circled area. It's significant enough I'm wary of driving the car -- it's still wet gasoline at the base of the carb, which you can probably see in the pic.

Paul Abbott rebuilt these for me 10 years ago and other than syncing every few years, they've been blissfully trouble-free.

Fuel shouldn’t be up that high, the float bowls are overflowing, Internal maintenance is required. It’s likely that filters are getting soaked with fuel as well. Check and adjust the floats and fuel pressure. Clean the outside stains, and replace or clean the filters.

Thanks @snbush67 -- appreciate it.

Does anyone know if there's a quick and dirty way to adjust floats? I will have time to dial them in perfectly in a few weeks (and need to buy the fuel measuring vials), but for now, in the interest of getting it on the road and not having gasoline spilling out of the carb, does anyone have a technique for getting that float set about right?

"Do a search" I said to myself. This has some good info.

If you haven't already, do consider this.


Good luck there.

No, because you have to take the top piece of the carb off to access the float...

Then you get to bend a tab.... hopefully you get it right the first iteration...
