Carburetor issue with Holley 650 double pumper

[moparnut74]

Hello. I have a carb problem with my Holley 650 double pumper. The engine will start however the idle drops right down and it quits after a minute or so.

I removed the manual choke and butterfly in the carb since it was closing on occasion. Are there any holes that need to be filled in ??

I took off the fuel bowls, cleaned the needle and seats and re-set the float levels. I have changed the fuel pump and fuel filter.



Thanks !!

Has it ever worked ? Is the timing set correctly ? Is the idle speed screw on the carb set properly ?

If you are starting it cold without the choke plate it will not stay running until there is some heat in the intake . Once it is warm it should idle OK though .
There are no holes that need to be filled in when removing the choke
