383 gas smell

Hey guys trying to reduce the gassy smell of my 68 383. I relize that old cars have some kind of smell, mine seams to have more. It is mainly stock rebuild using KB 400 pistons original intake and exhaust manifolds. I am running a MP electronic ignition and the original carter AVS 4426 carb witch I just rebuild. I set my 2 lower mixure screws at 2 3/4 out and the second upper single mixure screw at 1 1/4 turn out as per 1968 original service manual. (Got info online). I am pretty sure my timming is at 34deg total. Last night I fired up the car and the wife was complaining about how I stunk up the complete house. Can this be fixed or is it time fore a new wife? Thanks
