Hello all!
I am in need of some help or advice. I have been working on my 76 Pinto with a 2.3 for a few weeks now. This car had been sitting for about 5 years when I pulled it home. Long story short I had to end up replacing the head and cam. I took the head to a reputable shop and had them do all the head work and clean everything up and check it out. Installed the head and place everything back into place. I rebuilt the Holley 5200, installed the new fuel pump, cleaned the tank, and installed a inline filter to catch any rust which may be left over in the tank. I will be the first to admit I am not a carburetor man and never have been but I have torn a few apart and rebuilt them and have always managed to get them close enough to have someone adjust everything so that it would run properly. I fired up the engine and managed to keep it running long enough to break in the cam with the setup I had. (I am not sure how needed a break in on the cam is with the setup but I did it all the same.) I ran into one of my cousins that use to be a very good mechanic and asked if he would come adjust the carb for me. He said yes and came by and the before I even start the car he wants to pull it off. Well to shorten the story I end up buying a remanufactured carb and installing it.
Here is were we set today. The car will run if you choke it to death and yourself after a few minutes in the garage. I am pretty sure I have a vacuum leak but I am not sure where. I tried spraying some carb cleaner around all the intake runners, vacuum port, and vacuum lines. Never could really detect a change in RPM as the car is running rough flooding itself to death. I went a head and replaced the PCV valve and the hose running to it. Then I unplugged every line and put plugs on all the vacuum ports. The car is still the same with everything plugged off. The only thing I have not messed with in the testing is the egr. You can see it appears to be functioning with vacuum and it has a new gasket. I plan to try and build a block off plate tonight just to test and see if it changes anything. Anyone got any other ideas what might be causing my vacuum leak?
