Did all cars back in the early 70's and before STINK when they were running. I have a rebuilt orig carb on my 70. Built by a long time old timer worker on Chev only cars. The car is tuned up but I still get bad fumes when it is running. No really raw unspent gas fumes, just stinky burnt fuel smell is the best I can put it. After I drive the car or am around it while running I have to take a shower. Carb need adjusting? Timeing/Dwell need more fine tuning?
