Engine starting and running troubles..

ok so i found the culprit..... good news is the car is running bad news is it was a wast of time trying to find the problem, we found an old fuel tank on the farm that had been dry for some time... we set it up filled her with fuel.. a couple days ago i had my car towed home and used up a good portion of the tank getting it running smooth again, with the tank low i filled from the old fuel tank in the yard and found out the hard way that there was a bit of sedimentation in it and it ended up bypassing the fuel filter on the tank and in my car to plug both the needle and seats in both the holley and the eddy. so i partially choked off the hose on the secondairy side bowl (holley as mentioned above) and ran it hard for a bit then took the clamp off and it seemed to have flushed its self and sealed its self again, and isnt dumping the fuel down the secondaries while their closed.... or this is karma wont know till i drive it around a bit to see.
thanks for all the info it will probably come in handy in the future im sure knowing my luck
