This is a long shot, but I thought I'd give it a shot.

My demolition derby car has a '79 Buick 301 with a 2 bbl carb that appears to be fairly new. Problem is the car won't run. If I pour gasoline in the top, she will run for 15 seconds or so and than die. I removed the filter and it was falling apart. I suspect that it committed suicide and now I 8.3 million little peices of filter in the accelerator pump because the jets just don't seem to be squirting enough. Does it sound like I'm on the right track?

How hard is it to swap out the accelerator pump on a GM 2 bbl? One more question, does anyone have experience with running one of those goofy 2 to 4 barrel adapters? I have a good quadrajet and I wonder how that lil' 301 will run with the q-jet and adaptor.

BTW, the fuel pump is fine, so I know thats not the trouble.

Thanks guys............

You probably need to clean the entire carb. it can't hurt and it garentees you didn't miss something. tear ir down and shoot some carb cleaner though all holes and jet's untill it comes out clean on the other side. Reasseble and retry. good your self a good book like "how to modify holley carberators" for info on how to tune and rebuild.
