Gasoline Odor / Smell after use

[Mr. Chuck]

Recently rebuilt carb (minor, new gaskets & bowel control), now have smell of gasoline after car use, and parked for short time. Suspect gas vapor recovery system as problem. Inspection of lines to canister appear intact. Any ideas on best way to trouble shoot the problem. Carb shows no fuel leaks or excessive fuel in barrels after engine turn off.

Get it outside where the vapors can disapate, then start sniffing around where you were working. Check areas around the carb(fuel lines,fittings,vacuum hoses) and identify where the smell is coming from, and whether it's outside the carb or inside the air cleaner area.

The filter in the canister needs to be replaced on occasion and can cause the odor.

 

[Mr. Chuck]

Thanks for the ideas and quick responses; I have never changed the filter (didn't even know canister had one).

It's on the bottom. On the 77 (I don't know if your's is the same) the easiest way was to remove the chrome trim under the door, which gives you access to the botls that hold the splash shield in place that is under the canister. I don't remember how the bottom came off it, or if there was even a bottom for that matter, but the filter slides around a thin plastic bar across the bottom of the canister. Don't try to turn the bar or you will break it off.

Check for vaccuum leaks too. This can leak an odor. I had a bad brake booster on my old '73, and it was leaking vapors into the car after I shut it off.
