67 mustang jetting.
So i got a 67 mustang for my birthday but havent been able to drive it much becuase i smell horrible when i get out. i think its running kind of rich becuase when the engine gets hot it dies a little when i step on the gas. Any suggestions? do i need to re jet it? if so how? lol

RE: 67 mustang jetting.
There's not enough info to tell. It could be the accelerator pump circuit. Does it just drive like crap when it's warmed up, or only stumbles when you open the throttle? And does it do it worse if you open the throttle faster? What engine/mods and carb? Could be the wrong sized carb for the car as well

What type of carb are you working with? Does the car smoke? You may can adjust the carb...possible too much gas going into the engine. If you have a holly, adjust the side screws all the way in, then loosen 1/4 turn, then 1/8 turn in or out to tune.

That looks like maybe an Autolite. Not sure which one. And I am not sure how to tune those. I am sure someone will chime in that knows how. But it sure does sound like it needs a good tuning. Maybe even a rebuild kit.

On the left front mounting ear of the carburetor, there is an identification marking. The first character is a number, the year (1,2,3,4,5,6,7 etc), the second and third (or fourth if present) are letters (A, D, F, Z etc, and any letter or combination of A thru Z). We need those.
On the left hand fender apron is the VIN number. It is near the front in a notch in the fender. We need that too. It's also on your registration.
From the picture, I can see an electric choke andmissing vent tubes. It need a rebuild.
