Well if it smells that rich, it has to be rich, regardless of what your A/F gauge says.

I can tell you that mine started running rich like that, only sometimes though and now its pretty much all the time so I figure its most likley my O2 sensor. My carb is brand new so I doubt thats it. I'm gonna buy a new one and see.

Do you still have a cat(s)? My car has no cats anymore, and smells a little gassy from behind, but mines in basically perfect tune... runs great, plugs look right, decent mileage, etc, but theres some gassy smell there.

Just the lack of cats will make your car smell like that because theres always unburned fuel that gets to the exhaust system. If theres no cats to burn it off, you will get that smell.

Some gassy smell is normal w/o cats, but if its a really intense 'experience' though... like burning your eyes when you stand near the car, then I would at least check the condition of the plugs to see how its running, and check the timing as well.

Yep, no cats or any of the smog stuff for that matter and your right, there is always a little stinch when you have no cats. Car runs pretty strong even with the new 305. I've been pretty busy and it's been raining like hell down here in Florida so I have not had a chance to pull the plugs and check out whats up. In fact, I have not driven it since it started to be on the safe side. I will post my results this weekend.

I have the timing at 14* per Edelbrocks recomendations, I just havent had a chance to play with that number yet because I have been planing to get a full MSD setup.

BTW, it's been throwing an SES light at me too, I havent polled the ECM for codes yet but I bet its O2.
