Engine oil smells gasoline

On a "normal" car that is run regularly the usual suspects are:

1--bad fuel pump. A very dangerous situation which can and has caused crank case explosions

2--carb too rich, flooding, leaking needles, seats, etc, which is causing a too rich condition and leaking raw fuel past the rings

But in your case, where the car is stored and PROBABLY has been started and run for short times, etc, and as you describe under adverse conditions, probably a gummy, crummy carb, it might be really understandable that the oil is "not well."

Fix or replace the carb situation. Change the oil and filter. Run it long enough to get it fully warmed up, and then monitor it for a period.
