So I've been smelling gas lately, and this seems to be evidence that it is running way to rich.

I'm not sure how to modify the air flow muxture. I have a 1989 throttle bodied 305. This was discovered when i went to put on a new filter.

What parts should i be concerned about. I think of

Fuel filter
O2 sensor
Dirty injectors
Fouled spark plugs.
Timing.

Since the problem was found on the underside of the air cleaner, should I only be concerned about the valve timing, and things farther up the line?

Thank you in advance.

Looks old is all.

Might think about replacing your PCV valve.

hmm, PCV valve was done a year or 2 ago, but ill check it. I still hear it rattle.
