I have a Carter YF 2101 carburetor on my 261 engine and I am getting the smell of gas. I have noticed this more on really warm days. I have checked for leaks. I have looked at the carburetor with the engine running and immediately after turning the car off. I have lowered the float to cure a flooding problem. The car runs great otherwise.

What else should I be looking at?

All help appreciated, Pete

I would look over the entire fuel system underneath your car to make sure you don't have a leak there. Including the top of the tank where the sending unit is.

This is not a closed system and today's volatile fuel is designed for a closed system.

Check for leaks, but do not overlook the fact that the carburetor vents to the atmosphere and that's probably where the vapors are coming from.

People fear change because it threatens what they know, or what they claim to know.

A Carter YF 2101 doesn't vent to the atmosphere unless you count the open throat that the air cleaner slips over.

Yes, that is exactly what I mean.

To add, the vented gas tank cap.

Thanks for the responses. So, is there anything I can do about the smell?

If no obvious leaks, venting the area is all you can really do. Make sure that any connections to the filler and tank are not wet or leaking.

Several years ago, I had a 1980 Chevrolet Monza coupe and it had the 4-cylinder and otherwise well equipped. When I parked the car in the garage after driving, we had to deal with gasoline smell as well.

The solution was to leave the car outside until the engine cooled down, then park it in the garage.

The volatile gasoline of today is different than the gasoline of yesteryear.
