Carburator wont idle or run contunious

HI Guys



I was hoping some one could help with their best guess. In my below video I show an empty in line fuel filter as a cause of my problem.. I have remedied that now... I am using a gas can below the engine to supply fuel and a pump test overflowed a beer bottle with gas from the inline filter and line.



I can blow my air onto the inlet hose to the primary carb chamber and hear bubbling. I can run the engine briefly and during that time I get acceptable throttle response up and down.



problem it just wont idle.... it dies. and it stops even when I try to hold a foot level.. feels like fuel starvation.



Question don't these Holley 4150 carbs spurt fuel from a jet in the side of the barrel. I get no spurt when engine off . I rebuilt the bowls, set the levels and I did not open the body .. I rebuilt the carb just to start a clean out of the fuel system.

Okay it's not idle screw or vacuum leak !

 

HI "GT"

thanks for responding. I have tried the fuel spray tests. It seems there are no major leaks even though the trouble shooting guide at"""" Engine starts, then dies within a few seconds """"" is my problem. I have a brake gauge hooked up you as they suggest but I cant get out of the car fast enough to see it before stall.

Can you tell me gain specifically

A. do you currently have a Holley

B. does it seem to squirt. Cause I wonder if the body of the carb fouled?

thanks Tom

Do you mind if I get annoying. I apologize. I was hoping to learn from you and your carb. I would hope you could do one small favor. Could you go out to your stang pull off the air cleaner and yank on the linkage engine off. See if your jets will squirt?

Thanks tom
This will help me in my trouble shooting.

YES TOM !

thanks tom! Man a youtube as well! Thanks for being so nice. Of all the men out there helping and on different forms as well, nobody came thru with exactly that reaffirmation of carb theory. I can get the carb running on primed gas but I cant hold it and the engine dies.

When I go for the pump pull I get no Squirt. Never have, Cant see that its running so high rev on two / three second on primed aerosol fuel. So I wonder if its getting fuel some how. But with no squirt I'm guessing it has no fuel for constant idle.


I guess I will have to buy that 25 dollar can of Berrymans carb dip and go thru the entire carb soak.

What do you think?

Hi Tom

Well I did find the problem. It was me!! I placed the wrong gasket from the kit on the Metering block! Starved for fuel.

With primed fuel I can get it running and get strong throttle response. However I cant keep it from stalling , it lopes. I crank the curb idle screw very high to keep from falling out at its low point. then it spins back up again. A repeating cycle of 5 seconds? I worry it still may be the carb.



Some told me the timing is off from 12 year old gas in the old tank to current gas in a new tank. I have not tried that yet.

What do you think? Anyone?
