After reading all of the archieved posts on similar situations I still need some help with my specific problem.
My'73 (302 with 3sp manual) starts up and runs fine (loping idle due to cam) but runs well for anywhere between 5 miles and 50 miles (problem has happened as soon as ten minutes after driving to an hour after driving) and then it starts acting like it is out of gas (or has a bad fuel pump).
Once it dies, it is hard to start again (lots of pumping needed and heavy pedal once running). Put it in 1st gear and it will run for about 20 ft and bog down again..... over and over again until I limp home. Pulled the breather off and looked to see if I got a spray of gas when I manually worked the accelerator (it gets gas).
Some factors to consider in helping me diagnois is: I replaced the points last year with a Pertronix unit in distributor; I have a slight oil leak at the rear of the manifold; it seems to run better with the breather off (not for certain though).
I know that it could be a vaccum leak at the back of the manifold (or somewhere else) or could be trash in my tank/lines or even a coil heading south or fuel pump and plan on checking all of these this weekend, BUT why would it not start until it had been driven (well) for a while and why does putting it in gear and letting out on the clutch cause it to bog once this whole mess has started?
Any other ideas would help before I jump into this over the weekend.
Thanks,
Mac
