My son and I start this project 4 years ago and it is just finishing up now. I have included some pictures. I have alot of these, but on to the problem. I replaced the engine (305) from a mechanical fuel pump to a electrical one. I would have kept the mechanical one but there was no pump push rod where the pump goes. So, with that said, I can get the car to run if I spray starter fluid in the carb, but it dies when I stop that supply. First I flushed the gas out, and started with new. I tried using an electric fuel pump with a nice mallroy regulator to supply just the 6-7. But that didn't help. Then I tried to just give it fuel and bypassed the fuel pump (that I added) and the regulator. Just using the pump that is in the tank. Still nothing. Then I rigged up a gas can (gravidy feed) and supplied it directly into the carb. Still no go. I have replaced the QuadJet Carb with another, but it was used. But even used it gave the same results.

Any ideas out there?

 

Well, you're down to the short strokes now! A gravity-fed system should be perfectly adequate to fire and idle a motor- done it many times myself. I'm guessing you have a fouled up carb. Has it been sitting for a while?

First thing you need to determine is if you're even getting fuel into the float bowl. That's easy to check- pump the gas a few times as you look down the primary barrels of the carb (hold the choke plate open so you can see down there). Every time you stroke the throttle you should get two pencil-lead-sized streams of gas shooting in there. That's your accelerator pump. If there's no fuel in the carb's float bowl it obviously won't have any gas to pump in there.

Start there and report back.
