Gas Smell

[PaulProe]

Just got my Webers installed and working my way thru the tuning. Something I immediately noticed is the smell of gasoline in my garage. The car hasn't been running so it isn't due to fuel dripping or puddling. No leaks in the fuel system. But each carb is "open to atmosphere" thru the screen over the jets.

Is this something I will just have to live with or is there a solution?

Yes, you will smell evaporating fuel to a minor extent but check that they are not dripping after shutdown. If one or more carb is dripping for various reasons that will really become noticable.

Paul,

The next time that you notice the gas smell after engine shutdown, look down the throat of each carb and see if there is any liquid gas on top of any of the butterflys. If so, the carb that shows this characteristic could have a slightly high float level, a leaking float needle, or gas can be percolating out of the pump jet into the carb throat. You can measure the actual fuel level in the bowl by removing the top of the carb and measure the height of the float above the reference surface of the bowl. If the problem is a leaking float needle, that carb will have a higher than normal fuel level in the bowl. If the cause is gas percolation, it will usually occurs several minutes following engine shutdown after the engine heat soakback from the manifold causes the gas in the pump chamber to expand.
