Okay, so I have a 1968 Automatic mustang with a straight 6 bone stock. It had some miss problems and found ample amount of sludge in the tank. Cleaned this all out and blew out the line and installed a glass filter in the rubber line that runs between the hard line and the pump. Replaced plugs, wires, coil, cap, rotor, points, and fuel pump.
Still would miss here and there but still made a decent amount of power for what I was expecting out of a little 6 banger. So then I turned to the next part. Replaced the dual distributor with a rebuilt unit and rebuilt the carb personally. There was a lot of gunk in the carb and I assumed I fixed my problems. Car idles beautifully and is timed to 12 degrees with the advance unplugged and capped.
Now for the major issue. When the car is idling, I am able to increase the throttle slowly with no problem, will rev right up. If I punch down on the throttle it will spit and sputter, fire out the carb once and stay at a lower RPM and just sit there. Now, if I take the car out on the road, it feels like the car is permanently stuck in third gear, it struggles to get up to ten miles an hour and sits at the lower RPM whether you try to ease the throttle or floor it. Other oddity is if you are flooring it, eventually it feels like it kicks down in gear for a couple seconds and will start to climb, just to go back to the slow RPM again.
Finally, after driving it for roughly 5 minutes like this, there is a very strange odor, almost a cross between clutch and mouse/mouse nest.
Again, the car ran really well with just a slight miss and would die if it sat at idle for longer than three minutes prior to the rebuild of the carb, new rebuilt distributor and glass fuel filter.
I think the carb is just tired and worn out even after the rebuild but just wanted this forums expertise.
Any help would be greatly appreciated!!!!!!

have you done a compression test yet? Have you checked for Vacuum leaks? Good luck
